Hello!
I am setting up a natural convection boundary layer, where I impose a heat source (heat flux or fixed temperature) at a wall, but I don't know if the set up I am planning is good enough. In the figure you can see my initial set up, and I will use buoyantBoussinesqPimpleFoam. The BC's I am imposing are:
If you think that I could improve my simulation by modifying some parameters, I would be grateful! Thank you! |

Hey Agustín,
I want to simulate the same case. Do you have some News? Do you have improved/modified your parameters? Kind Regards! |

Hello Dominik,
I am still dealing with the boundary conditions. I am imposing inletOutlet for temperature in the free stream region and inlet, and a zeroGradient at the outlet. For velocity I set zeroGradient, and the pressure is now my problem. Recently I have know about fixedFluxPressure and buoyantPressure (the last one not available in 2.3.x), and I want to use them and see their effect. In the other hand, the solver is always a pain. I have developed an incompressible solver which is not working ok at all, and there is other option: to use buoyantPimpleFoam with an incompressible configuration. And you? How is it going on? |

Hi Agustin
I am working on the same problem, but I am facing problems to give boundary conditions for pressure and velocity at inlet and outlet. Please share the boundary conditions. |
