Hello everyone, I trying to find the most suitable solver to run a simulation of 2 gases at different temperatures inside one pipe (one flow of gas A at a high temp, and a sheath flow of gas B at room temp), and see the effect of the temperature on the flow itself becuase of the density differences resulting from the temperature differences. I don't want to simply see how the temperature is changing.
the ultimate goal is to minimize the wall contacts of gas A. I have basic knowledge in Openfoam, ive only used simplefoam before. |

Hi,
Based on your description I guess gas A and gas B have different species as well? In that case I guess you would need to run something with rhoReactingBuoyantFoam to have all physics involved modeled correctly. Otherwise if it is just a single species but at different temperatures, buoyantSimpleFoam or buoyantPimpleFoam can be used. Best Regards, Tom |

You can consider using solver reactingFoam with reaction feature turned off. This allow different species and temperature inlet boundary conditions.
