The k-epsilon model -- CFD Online Discussion Forums

Luis Guest Posts: n/a	The linear k-epsilon model assumes that the turbulence viscosity is linked to the turbulence kinetic energy and dissipation via the relation: μt=Cμρk^2/ε Where Cμ is a constant (k-e Turbulence model constant). However, this linear model is inappropriate for swirl flows. Hence, a Cμ as a function of a shear parameter is usually defined to represent better those type of flows. Therefore, I would like to ask if is a way to define Cμ as a non constant parameter (as a function) using CFX 5.6 or 5.7
