Greeting everyone,
I'm currently conduct study using twoLiquidMixingFoam to study mixing of liquid. Unfortunately, the solver is non-boussinesq aprroximation. Is there anyone implement boussinesq approx successfully into twoLiquidMixingFoam solver? I tried modify UEqn file by removing rho term in the equation and multiply with a constantRho, the solver works but the result is incorrect compare to journal study. Thank You. |

You may set the thermophysical properties in a way that is practical identical to the Boussinesq approximation. I did it not for the solver you mentioned, but compared buoyancyBoussinesqPimpleFoam with buoyancyPimpleFoam. They were nearly identical.
