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
