Default Simulating from EVC to EVO in exhaust ducts
Posts: n/a
Hello, I'm simulating the discharge run of an ICE (star CD vers 3.26). My troubles are in relation to the boundary condition to impose at the end of the exhaust duct. I use a calculated condition from a 1D simulation code (like Wave or GT-Power) defined at the same section that i have in the 3D model (end of the exhaust's primary pipe). The question regards if it's better to impose a Flow Mass condition (Inlet), Total Pressure or Static Pressure.

Thanks to everyone form your help.
