Hi there,
I am approaching to run a 2D simulation of a profile. I initialize the flow with simpleFoam and then use steady-state fields as initialization for pimpleFoam. My question is how to calculate k and omega at inlet for simpleFoam. Experimental data are:
Should I use the values as for a 3D simulation? k=3/2*(U*I)^2= 0.00239 omega=sqrt(k)/L=sqrt(k)/(0.038*dh)=0.32 do these values make sense for a 2D simulation? Thanks Alberto |

The numbers are the same for 2D and 3D cases:
