Excellent Ansys Fluent Compressible Flow - The Definitive Guides. The boundary conditions used by ansys fluent at outflow boundaries are as follows: It should be used for gas flows where the mach number exceeds 0.2 or where compressibility effects, such as acoustic waves, are important.
Open workbench and drag “fluid flow (fluent)” toolbox to the “project schematic” window 2. The energy equation needs to be turned on since this is a compressible flow where the energy equation is coupled. Fluent offers a modern, user.
