Advanced Seminar: Vehicle Thermal Management in GT-SUITE

This one-day free seminar is primarily targeted to existing users of GT-SUITE for modeling of Vehicle Thermal Management systems, but may also be interesting for individuals considering the use of GT-SUITE for this purpose. The seminar will highlight some of the new features of GT-SUITE V7.0 that specifically relate to the modeling of VTM systems. In addition, the course will cover some VTM modeling topics that may be of broad interest. Each student will be seated at a computer, which may optionally be used to follow along with the instructors demonstrations.

1. New Features of V7.0 that relate to thermal management:

a. Easy creation of Model files from CAD geometry using GEM3D: The participant will see a demonstration of the GEM3D pre-processing tool which enables efficient creation of GT-SUITE piping network models from an imported CAD geometry file.

b. Fast and accurate modeling of underhood thermal management systems using COOL3D: The participant will be introduced to the quasi-3D approach to modeling underhood cooling airflow within GT-SUITE. This will include a demonstration of the COOL3D pre-processing tool which allows the components of the underhood compartment (radiator, fans, front fascia, engine block, etc) to be easily created in a 3D CAD environment. Then the tool automatically creates a GT-SUITE model which can be integrated with a cooling system model giving a quasi-3D solution to air flow through and around the underhood components.

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
Discretization and flow modeling
Other topics proposed by the participants.

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?

The training will begin with a typical GT-POWER engine model at laboratory conditions (i.e. imposed intercooler and EGR cooler outlet temperatures) and a typical underhood model (as would be used by a VTM cooling system group). The underhood heat exchanger pack will be modeled in both simple 1D and sophisticated 3D underhood models (created in COOL3D). The methodology will be equally applicable to both detailed engine models and fast running mean-value engine models.

WHO SHOULD ATTEND?

· Engine performance engineers who study turbocharged engines, both SI and diesel, at non-laboratory conditions.

· Cooling (VTM) system engineers who wish to work more interactively with their engine performance colleagues

This training class will not teach how to build basic engine and underhood HX pack models. (Separate training classes are regularly available for model building.) Please do not hesitate to contact the instructor if would like to discuss if this class is a good match for you.

Because registration is expected to be high, first priority will be given to commercial customers, and the number of attendees per company may need to be limited. However, we encourage all who are interested to register, even if on the waiting list; we will try to find a way to accommodate all registration requests.

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’. 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
Discretization and flow modeling
Other topics proposed by the participants.
