tstorm is on a distinguished road
Has anyone written successful UDF source equations for turbulence kinetic energy (k) or turbulence dissipation rate (epsilon)?

I've tried writing mine based on the k-e equations here (http://www.cfd-online.com/Wiki/Standard_k-epsilon_model) but velocity profiles in the boundary layer don't match the Blaussius curve.

Thanks!
