WEBINAR: Modeling The Underhood In GT-SUITE Using COOL3D

This webinar has been postponed to 23rd June at 11:00 Berlin time.

The methodology used within GT-SUITE to simulate underhood airflow and heat exchange offers predictive capabilities, yet at computational speeds that make these models useful for simulation tasks usually performed with fast running 1-D models (i.e. long transient drive cycles).   At the same time, the COOL3D pre-processing tool provided within GT-SUITE simplifies the model building effort such that it is actually faster and easier than building a typical non-predictive 1-D underhood model.  This free webinar will introduce the state-of-the-art underhood simulation technique used in GT-SUITE.

The webinar will last roughly 1 hour (from 11.00 to 12.00 Berline time) , and will explain how GT-SUITE can overcome the limitations of the 1-D underhood modeling approach typically used in industry today using a 3-D model building tool called "COOL3D".    The underlying technology of COOL3D will be explained and a demonstration of the underhood modeling process will be given.  The application of COOL3D and GT-SUITE to predict the results of changes to component sizes or layouts will be demonstrated.  In addition, the easy integration of underhood models into larger GT-SUITE vehicle system models for use in steady-state or transient simulations will be discussed.

WHO SHOULD ATTEND?

The webinar is aimed at CAE simulation engineers or managers within the vehicle industry who currently perform simulation of the underhood compartment at any level, or those who think they might need such capability in the future.  This may include those who have responsibility for underhood cooling module layout and component design, as well as those with an overall vehicle energy management focus (i.e. fuel economy over transient drive cycle).  This webinar is also appropriate for underhood component suppliers, who may wish to study the impact of a new design alternative or new control strategy on fuel economy (proof-of-concept).

• Engine start-stop modeling (simulation of the engine at standstill)

• Improvements to SI predictive combustion modeling (SITurb)
• Review of tumble modeling its usage in SI combustion modeling.  (Some applicability to diesel swirl too.)
• Introduction to multi-cycle combustion analysis, especially for SI knock analysis (final version may not be released until late 2010 or early 2011)
• Multi-mode combustion (i.e. switching between different combustion models cycle-to-cycle
• Review of cylinder pressure analysis and burn rate calculation (This is an area where we observe frequent modeling errors)
• New injection modeling options for diesel injection profiles

Realistic Modeling of CAC and EGR Coolers and their Effect on Engine Performance

This one-day free seminar will focus on improved modeling of turbocharged engines by integrating sophisticated models of the charge air cooler (CAC) and EGR cooler. The resultant model takes advantage of the multi-circuit capability of GT-SUITE so that there is only a modest increase in computational speed when detailed CAC and EGR cooler detail are added to an engine model, thus making this methodology practical for a wide variety of simulation studies. This class is primarily intended for engine performance engineers, and as such, no previous experience with heat exchanger or underhood modeling is required. The training facility will provide a computer for each attendee.

The fully integrated model is applicable to both steady state and transient simulations and enables modeling of complex interactions such as engine derating due to turbocharger over speed and surge. The more accurate prediction of engine inlet temperature is also relevant to combustion topics such as ignition delay for predictive diesel combustion and knock in SI engines. The integrated model can be used to address a variety of questions such as:

1)      What is the real torque curve at 1000 meters altitude on a 35C day?

2)      How much would a bigger or better CAC improve engine performance?

3)      Is engine performance change from vehicle speed and head/tail wind?

4)      Is the optimal cooling fan control strategy for the cooling system also optimal for the intercooler?

5)      Is the CAC performance degraded when the nearby AC condenser is rejecting heat? Can negative interactions be reduced by changing their relative positions?

6)      How does the EGR cooler size, and coolant flow rate and temperature through the EGR cooler, effect, the engine?

Modeling Performance and Acoustic Effects of Engine Intake and Exhaust Systems using GEM3D featuring New Slicer Capabilities

This is a FREE training seminar. Due to the limited room capacity, seats will be allocated preferentially to OEMs and suppliers. GEM3D is a CAD-based pre-processing tool that is designed to assist users in the modeling of flow components in GT-SUITE. In this class, users will learn how to use GEM 3D to model various exhaust and intake systems, including manifolds, mufflers, resonators and airboxes. This is done by importing CAD files (STL format) or building the system from parametric templates and discretizing the system into a network of components (e.g., pipes and flowsplits) that can be imported into GT-ISE for use in a GT-SUITE model file. Special attention will be paid to the new "slicer" capabilities of GEM3D, in which the ability to discretize imported STL files into pipes and flowsplits has been added in v7.0. This feature was available previously in a separate tool, called the ‘3D Discretizer’. In addition to adding the capabilities of the ‘3D Discretizer’ to GEM3D, the features have been streamlined to provide faster and more efficient discretization. Also, time will be left at the end of the day for open discussion and questions regarding acoustic analysis and/or any other topics relating to GT-POWER and GT-SUITE.

1. Introduction to GEM3D:   

• Purpose and Capabilities
• Viewing and Navigation (rotation, zooming, panning, viewing windows)

2. Discretization of an intake manifold into Pipes and Flowsplits from an CAD file (STL format)

3. Building of a Muffler and Exhaust System Shell:   

• Importing and creating shells
• Addition of pipes, baffles, sleeves, perforates and absorbing wool
• Exporting final model to GT-ISE

4. Future advancements

5. Open forum for discussion of all GT-POWER and GT-SUITE related topics. Potential topics include:

• Acoustics

Realistic Modeling of CAC and EGR Coolers and their Effect on Engine Performance

While this class is currently full, we are considering alternative arrangements for those on the wait list.  Please click ‘Join Waiting List’ above if you are interested in this seminar.

This one-day free seminar will focus on improved modeling of turbocharged engines by integrating sophisticated models of the charge air cooler (CAC) and EGR cooler. The resultant model takes advantage of the multi-circuit capability of GT-SUITE so that there is only a modest increase in computational speed when detailed CAC and EGR cooler detail are added to an engine model, thus making this methodology practical for a wide variety of simulation studies. This class is primarily intended for engine performance engineers, and as such, no previous experience with heat exchanger or underhood modeling is required. The training facility will provide a computer for each attendee.

The fully integrated model is applicable to both steady state and transient simulations and enables modeling of complex interactions such as engine derating due to turbocharger over speed and surge. The more accurate prediction of engine inlet temperature is also relevant to combustion topics such as ignition delay for predictive diesel combustion and knock in SI engines. The integrated model can be used to address a variety of questions such as:

1)      What is the real torque curve at 1000 meters altitude on a 35C day?

2)      How much would a bigger or better CAC improve engine performance?

3)      Is engine performance change from vehicle speed and head/tail wind?

4)      Is the optimal cooling fan control strategy for the cooling system also optimal for the intercooler?

5)      Is the CAC performance degraded when the nearby AC condenser is rejecting heat? Can negative interactions be reduced by changing their relative positions?

6)      How does the EGR cooler size, and coolant flow rate and temperature through the EGR cooler, effect, the engine?

Modeling Performance and Acoustic Effects of Engine Intake and Exhaust Systems using GEM3D featuring New Slicer Capabilities

GEM3D is a CAD-based pre-processing tool that is designed to assist users in the modeling of flow components in GT-SUITE. In this class, users will learn how to use GEM 3D to model various exhaust and intake systems, including manifolds, mufflers, resonators and airboxes. This is done by importing CAD files (STL format) or building the system from parametric templates and discretizing the system into a network of components (e.g., pipes and flowsplits) that can be imported into GT-ISE for use in a GT-SUITE model file. Special attention will be paid to the new "slicer" capabilities of GEM3D, in which the ability to discretize imported STL files into pipes and flowsplits has been added in v7.0. This feature was available previously in a separate tool, called the ‘3D Discretizer’.

After the introduction to GT-SUITE in the Day 1 training, this Day 2 training is intended to offer a basic overview of thermal management modeling with GT-SUITE.

1. Modeling a Complete Cooling Circuit:
   • Major components (pipes, pumps, fans, heat exchangers, valves, accumulator tanks, etc.)
   • Assembling components of a basic cooling system
   • Performing steady state and transient analysis
   • Calibrating a model to experimental data

2. Modeling an Engine Internal Cooling Circuit:
   • Building cooling flow network including all significant components.
   • Assembling lube circuit and friction model (effect on fuel consumption)
   • Integration with GT-POWER
   • Discussion & Comparison with 3D CFD Results

3. Integration of the 1-D Flow Model with an Engine and Vehicle Model for Transient Simulation:
   • Integration of a mapped engine and vehicle (with driving cycles and drivetrain warm-up)
   • Incorporating thermal management control strategies

(Underhood Simulation: If time permits at the end of the class, the instructor will introduce a quasi-3D underhood flow model using the CAD-based preprocessing tool, COOL-3D. This tool allows for the solution of the transient air flow around and/or through grilles, blockages, stacked heat exchangers, fans, and the engine block. This tool is used for example for scaling heat exchanger size.)

GT-SUITE Lubrication Circuits Modeling: Day 2

After the introduction to GT-SUITE in the Day 1 training, this Day 2 training is intended to show engineers how to model a lubrication circuit in GT-SUITE. The participant will be able to understand in detail the advantage of GT-SUITE compared to previous modeling methodologies of lube circuits. The participant will also discover a new way of creating an oil circuit model directly from a CAD File, which is a true alternative & technological breakthrough to efficiently generate 1D lube circuit models.

1. Building a Lube Model in GT-SUITE:
The participant will learn how to construct a lubrication model from scratch, in focusing about specific models of lube circuit such as oil passages, bearings, relief valve, and pump.

2. Analyzing Results:
The participant will learn how to analyze results of a lubrication model, including a breakdown of the oil flow distribution to various consumers, as well as performing an engine speed and temperature sweep to see how these variables affect results.

3. Demo Showing Major Capabilities:
The instructor will show that the following types of oil circuit analysis can be performed in GT-SUITE, all of which are derived from the same model built in the morning session
   • Steady state
   • Filling
   • Transient thermal oil response (both temperature and engine speed changing)
   • Pump power consumption over driving cycle

(Demo of CAD Based Modeling: If time permits at the end of the class, the instructor will demonstrate how to transform a CAD File into a 1D lubrication model in GT-SUITE using the pre-processor GEM-3D.)
