Dear Foamers,
I need your help. I want to simulate a case with a bo dimensions 5m, 3m, 1m. Which has one inlet and one outlet, 5 mm and 10 mm diameters. CO2 is coming from the inlet with constant velocity 1m/s. At the initially, the domain is filled with N2 and O2. This means the system has tree gases. There is no reaction and gases are compressible, therefore I selected the buoyantReactingFoam solver. The outlet is opened to the atmosphere. I need your help to set the correct boundary condition for the outlet. Here are the outlet boundary conditions, U - pressureInletOutletVelocity p - calcualated p_rgh - prghTotalHydrostaticPressure; I want to know how to match the outlet boundary to the atmospheric pressure ? Best regards, Prasanna Welahettige. |
