Parameters of turbulence in the laminar simulation buoyantBoussineqPimpleFoam
Hello everyone. I'm trying to simulate the transient and laminar natural convection in a cube. I'm using buoyantBoussinesqPimpleFoam solver. I wonder why even as a RANS model by setting must specify values for laminar alphat, kappat, nut, etc..? Thank you!
even the laminar case is a turbulence model. laminar is a dummy turbulence model that does not use these values.
according to the source of laminar, you don't actually need to create nut or any of the other fields, since the fields k, nut, and epsilon are created internally. the only field you need to specify is kappat, because it is not really part of the turbulence model but the temperature equation. it is used to create the effective conductivity
