Jan 3, 2012 · Boussinesq eddy viscosity assumption In 1877 Boussinesq postulated [1] [2] that the momentum transfer caused by turbulent eddies can be modeled with an eddy viscosity. This is in …

Hi all, I have been using buoyantBoussinesqPimpleFoam for some time now quite happily in OpenFoam 6 and earlier. However, I would like to be able to

I have a question about the Boussinesq approximation. I know that the approximation is rho = rho0* ( 1+beta* (T-T0)) where rho0 is the reference

Nov 24, 1998 · In computing bouyancy induced or bouyancy affected flow, many worker employed boussinesq approximation in their computational model. If computation is

Hi, I am simulation a big entry hall and try to activate the variable density option. Under Material Air I activate "boussinesq" and set the

Hi Everyone! I am simulating cooling of a component by natural convection. The component is placed in rectangular box at middle location with

Hello Everyone, Please forgive me if my question is too simple. I am very new to openFoam. I want to modify the buoyantBoussinesqPimpleFoam solver,

Hello everyone, I am trying to solve 2D Rayleigh-Benard convection with OpenFOAM 7. I am using buoyantPimpleFoam with boussinesq model for equation of

Hello, I'm using fluent and trying to solve a problem of heat transfer with natural convection. In my problem there are two fluids, how can I apply

Hi, I am trying to model natural convection in a closed domain using the boussinesq approximation with Fluent. I am wondering which value I must
