PowerTHERM

PowerTHERM® is coupled with PowerFLOW to provide a complete, extensively validated digital thermal management solution. Renderings in PowerTHERM have the ability to predict surface temperatures and heat fluxes generated by heat radiation, conduction and convection. The combination of PowerFLOW with PowerTHERM enables engineers to accurately predict temperatures and visualize the flow and temperature fields for the entire vehicle. Engineers can then identify problem areas and provide recommendations to improve the design. Rapid turnaround time for simulation and model creation allows engineers to quickly make design changes to the baseline and evaluate the improvements in thermal performance. PowerFLOW's unique, inherently transient Lattice Boltzmann-based physics allows thermal simulations to accurately predict real world transient airflow conditions on the most complex geometry.

Add on capabilities are available with PowerCOOL to model heat exchangers such as automotive radiators and charge air coolers and used in instances such as cooling the underhood. When coupled with PowerFLOW simulation, engineers can predict the calculated heat exchange between the air flow and the heat exchanger. The result is provided as the temperature of the coolant at the inlet of the heat exchanger (top tank temperature) or the heat rejection. Other results include distribution of air parameters like velocity, temperature, and density on the surface of the heat exchanger as well as coolant temperature distribution within the heat exchanger. These results provide essential information needed for positioning heat exchangers, understanding operation and optimizing overall underhood design of a vehicle.
