Simulating positive-displacement compressors allows you to study the phenomena that affect efficiency, including leakage flows, viscous losses, and pressure pulsations. However, the complex geometries and moving components of compressors can be challenging to model. CONVERGE’s unique autonomous meshing capabilities make it easy to simulate the complex motion of positive-displacement compressors with minimal setup time.

With large eddy simulations (LES), detailed chemistry, and sufficient grid resolution, CONVERGE can resolve turbulence chemistry interactions without explicitly assigning a sub-grid model to account for the interactions. Because LES and detailed chemistry can be computationally expensive, CONVERGE features several acceleration strategies to speed up your simulations.
