GT-COOL Training – Germany

This course introduces the capabilities of GT-COOL and its application to thermal management system design and analysis. Component models including pipes, pumps, fans, heat exchangers, and thermostats will be described while building a basic cooling system. Advanced topics such as GT-COOL/GT-POWER coupling will also be discussed. Each student will be provided with a computer.

1. Introduction to GT-COOL
   • Major components (pipes, pumps, fans, heat exchangers, valves, accumulator tanks, etc.)
   • Assembling components of a basic cooling system
   • Performing steady state and transient analysis
   • Integration of a mapped engine and vehicle (with driving cycles and drivetrain warm-up performance)
   • Calibrating a model to experimental data
   • Incorporating thermal management control strategies
   • Building custom parts from mass and boundary condition objects

2. GT-COOL/GT-POWER coupling
   • Linking a detailed engine and cooling system at 3-D finite element cylinder structure (including cylinder liner, head, piston, valves, and ports)
   • Multiple circuits applied to heat exchangers (charge-air-cooler, EGR cooler, oil cooler, etc.)
   • Understanding the two levels of coupling fidelity and their tradeoffs
   • Capturing critical engine/cooling system interactions and their effect on overall performance
   • Focusing on specific interactions (EGR over-cooling, charge-air under-cooling, aftertreatment device warm-up, friction during warm-up, passenger comfort, etc.)

3. Increasing productivity with GT-COOL
   • Using GT-POST effectively (plots, tables, 3D viewing, system wide results)
   • Building models to share with OEM’s/suppliers (including GT-POWER coupling and encryption)

**The class is intended for those who already have a working knowledge of GT-ISE (minimum requirement: completion of GT-COOL or GT-POWER tutorials).
