Details

The biggest challenge in fuel cell ejector design is to ensure the recirculation rate. To optimize the ejector design, the ejector flow field was simulated with Ansys Fluent.

Benefits

In this presentation, you will learn how a Design-Of-Experiment (DoE) was performed to optimize or maximize the recirculation rate. Geometric parameters were created, modified and the recirculation rate was evaluated. Complete automation of the entire simulation process resulted in a significant reduction in simulation effort.
