In this video you will learn how you can enable compressible flow in Discovery. Discovery provides compressible flow modeling capabilities for subsonic internal flows. However, there may be cases where the flow becomes transonic or supersonic due to a flow constriction in the fluid domain. You can use Discovery to solve internal flow applications such as high-speed gas flows or gas flows with large temperature variations, flows through orifices or other flow constrictions, and exhaust systems with high temperature ranges.
