Powertrain Component Heat Distribution Modeling

This class is intended for users with previous experience or users who participate in this free-of-charge Introduction Training.

This class will introduce the use of GT-SUITE software for modeling the distribution of heat within the engine thermal structure. Engine heat distribution models allow the prediction of heat rejection to coolant and oil at any operating condition, and may be used to study concepts for reducing fuel consumption by optimizing energy flows to minimize friction during transient warmup events. The course is targeted towards engineers with responsibility for powertrain cooling, friction reduction, or total vehicle energy management.

This course will cover the process of building and calibrating an engine heat distribution model, beginning from engine CAD data. The process involves significant use of the 3D pre-processing tools of GT-SUITE (GEM3D and GT-SpaceClaim). The following are the primary topics to be covered:

Conversion of coolant jackets from CAD Data
Conversion of block/head thermal masses from CAD Data
Modeling the cylinder structure with 3D finite elements
Calibration of flow distribution & heat transfer
Modeling map based engine friction depending on system temperatures
Integration with engine performance model
