I modeled two different electronic modules with SiC diodes to be used in pulsed power applications. Cooling in this high power application is provided by natural convection in a bath of oil. SolidWorks was used to construct a computer model and Cosmos FloWorks was used to simulate heating and natural convection in the oil. I applied two 80 W pulses to the modules and calculated temperature increases of approximately 60 C or less. I also simulated modules heated with a periodic signal over a 60 second period. Results were inconsistent with expectations, casting doubt on the merit of this simulation approach with Cosmos FloWorks.
