Turbulent(eddy) viscosity -- CFD Online Discussion Forums

Jongmin Choi New Member Jongmin Choi Join Date: Jan 2016 Posts: 14 Rep Power: 10	I need to specify turbulent viscosity ratio() for using k-epsilon model. I could know the dynamic viscosity from the information of the material. However I don't think that eddy viscosity is a property of the material. I found that eddy viscosity depends on the geometry and flow. Could you let me know how I can determine the Turbulent(eddy) viscosity? Is there any equation for determining the turbulent(eddy) viscosity????
