Hi there,
I want to model the heat transfer in a pump with the chtMultiRegionFoam-Solver. As the temperature range is pretty wide, I want to use temperature-dependent material properties. I already studied the chapter about thermophysical models in the user-guide, but that did not really help me, because everything is described quite short. Could someone please help me by giving a short description of the usage and the differences between the following four temperature-dependent property models? -Basic thermophysical properties -> hPolynomialThermo -Basic thermophysical properties -> janafThermo -Transport properties-> polynomialTransport -Transport properties-> sutherlandTransport Another thing I would like to know is: In which way is it possible to use temperature-dependent properties for the solid regions (especially with the chtMultiRegionFoam-Solver)? The thermophysicalProperies-dictionaries are only located in the constant directories of the fluid regions, so how can I model the behaviour of the solids? Thanks for every answer that is posted! Greetings Sebastian |
