Eddy Viscosity
Hi friends, I am modeling free surface transient water flow problem with CFX. I am applying inhomogeneous model of multiphase free surface and a homogeneous k-eps turbulence model. As the time progresses (say after 1, 2...5, 10 seconds of results Water eddy visocity goes on increasing with time. Why does that happen ? length scale of water is 0.07m . what i suppose is Eddy dissipation is not proper on the boundary. Is that the fault with turbulence model ?
