Powertrain Cooling

GT-SUITE is the ideal modeling platform for powertrain cooling analysis. GT-SUITE models can be used to predict heat rejection to coolant, oil, and ambient, before engine hardware is available for physical testing. These models utilize a built-in finite element cylinder structure allowing for more accurate predictions of heat flow. These models may also be used to analyze heat distribution (warm-up) through the engine thermal structure during transient drive cycles. Construction of GT-SUITE engine thermal models is enhanced by powerful 3D tools for converting CAD geometry into GT models.
Product Highlights
- Easy-to-use parametric finite element cylinder structure
- Cylinder structure transfers heat with combustion gas, coolant and oil circuit
- Liquid circuits and thermal masses built semi-automatically from 3D CAD data
- Flow solution is based on Navier-Stokes equations (robust and stable)
- Always solves energy equation (thermo-hydraulics)
- Stable even with zero flow and thus “standing water” presents no difficulty
- Heat distribution model easy to integrate with full vehicle models for transient drive-cycle analysis
