Regarding low-reynolds number modelling

Dear all,
I have developed the code for low-reynolds number modelling. Jonson-launder modelling is used. I am solving for channel flow. I have given the following boundary conditions: Inlet: U=1.0, V=0.0; K=1.5*0.05*0.05; eps=(c_mu^3/4*k^3/2)/(0.42*yp) yp-first grid poing location. Outlet: D(phi)/dx=0.0; phi=U,V,K,Eps; At the walls: no-slip boundary condition for velocities, K=0.0, Eps=0.0; I am getting very low values of k, eps, nu_t. It seems to be like laminar flow. Plz suggest me in this regard. Thanks in advance. Sincerely vishnu |
