Fluid properties channel-flow #177

|
Can anyone tell me where the fluid properties (density and dynamic viscosity of the fluid) are set in the case of the channel-flow? |

This is controlled by the Reynolds number. Xcompact3d uses normalised values / equations so for a given geometry, fluid and reference velocity this will set your Reynolds number. Unless solving a variable density case (e.g. the low Mach number solver) the normalised density will be 1 everywhere. |

Hi, I have some doubt in setting the parameter of turbulent channel flow,especially the steps of rotation and the rotation speed. Is there any tips in setting these two parameters? |
