I am simulating a scour below pipelines using sedFoam ,the turbulence model is k-omega.
But I don't know how to set turbulence k-omega boundary. some information domain : 1m*0.2m cylinder diameter D =0.04m water depth = 0.15m; I =5% turbulence length L=0.07*D inlet:velocity : u=uf/K*log(y/z0) uf=0.011m/s k,omega : zeroGradient; outlet:velocity :zeroGradient; k,omega :zeroGradient; cylinder: velocity :fixedValue uniform (0 0 0); k=1.5*(U*I)^2=1.5e-4; omega = Cmu^(-1/4)*k^(1/2)/L= 7.985; top boundary is set zeroGradient and the bottom is similar to the cylinder using wallFunction. Can someone check my boundary conditions and tell me where i'm wrong? Link with simulation(https://www.dropbox.com/s/wyrjairctj...pipe1.zip?dl=0) |
