User-defined k or epsilon? -- CFD Online Discussion Forums

October 12, 2009, 13:45	User-defined k or epsilon?	#1
tstorm Member Join Date: Apr 2009 Posts: 78 Rep Power: 17	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!
