Temperature Dependent Fluid PropertiesI am trying to run a model with buoyantSimpleFoam with temperature dependent material properties but as a newbie I do not know where to start when editing the thermophysicalProperties file. I have the model running without any issues with constant properties but I need to model them as temperature dependent.
It seems that it is possible, since Chapter 7.1 of the user guide says that Cp can be defined by a polynomial using "hPolynomialThermo" and the thermodynamic transport properties with "polynomialTransport". If someone could provide an example, that would be a huge start. Thanks for the help |

Hi, dear eliwide, you can reference to the buoyantBoussinesqSimpleFoam solver, which the rho is dependent on the temperature.

tempreture-dependent density for incompresible LESHi,
I am using incompressible LES solver for flow over step simulation. I have added the turbulent heat equation to the solver but still I don't know how to implement a temperature dependence for the density. Can anyone tell me how to employ a density with a linear dependence on temperature (without using the OpenFOAM compressible codes)? |

hello;
I want to simulate an incompressible nanofluid flow with heat transfer using simpleFoam (i.e. solver includes an energy equation). The conductivity and viscosity of the fluid is temperature dependent . I don't know haw can modify the solver and case directories to these properties become temperature dependent :confused:;you had similar problem, if you was succeeded in resolving would you help me:o? thanks kind regards |

Hi,
I am new in using OpenFOAM. The problem I am looking at is a freezing process of foods. So it is a solidification problem with temperature dependent properties. Any information in regard to the temperature dependent properties? |
