July 20, 2014, 10:38	Turbulence viscosity UDF	#1
lehoanganh07 Member le hoang anh Join Date: Oct 2012 Posts: 96 Rep Power: 14	Hi, I am using k epsilon model for cavitation model. In order to modify the turbulence viscosity with the compressibility effec, I use the Reboud function as: cmut= f(rho) * cmu* kk/epsilon In that f(rho)=rho_liquid+rho_vapor(1-void)^n I tryed to make the UDF as in Fluent UDF manual: DEFINE_TURBULENT_VISCOSITY(name, c,t) But I dont know how to call the density of phases: liquid and vapor in the code in order to calculate the density function. Could you help me how to do this? Thank you very much! zlw306 likes this.
