Efficient Digital Thermal Solutions for Vehicles

Thermal analysis reveals the heating and cooling behavior of devices when in use, and is essential for ensuring that products operate reliably in real-world conditions. PowerFLOW supports rapid simulation of thermal management systems with two add-ons – PowerTHERM and PowerCOOL – for thermal analysis.

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

Using the PowerCOOL add-on to PowerFLOW, you can model heat exchangers such as automotive radiators and charge-air coolers for under-hood cooling analysis. When coupled with PowerFLOW simulations, the results enable you to 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 heat exchanger inlet (top tank temperature) or the heat rejection. Other results include the distribution of air parameters like velocity, temperature, and density on the surface of the heat exchanger; and coolant temperature distribution within the heat exchanger. These results provide essential information needed to position the heat exchangers correctly and optimize the overall under-hood design of a vehicle.
