Mobility concepts are transforming and electric cars is playing an increasingly important role. However, challenges come along with this transformation process.

Electric motors for high-performance cars need to be cooled. During operation, losses occur and thus the motor heats up. Components like permanent magnets or isolation material impose thermal limits on the entire motor. Hence, to enhance performance and use resources efficiently adequate cooling strategies for electric motors are required.

Direct cooling is one possible cooling strategy for electric motors, meaning coolant is applied close to the heat sources. This promises efficient heat removal. The Institute for Reactive Flows and Diagnostics experimentally studies subsystems of direct cooling systems to understand its dynamics and improve numerical simulations using laser diagnostics.
