Turbulent non-Newtonian fluid flow using k-w model
 
Hi ! I am working on the implementation of 1998 k-w model for the turbulent non-Newtonian flow. As CFX42 doesn`t allow to solve shear rate dependent viscosity with non-Newtonian fluid flow I am using user scalars for k and omega and writing the source terms in USRSRC and modifying my viscosity in USRVIS. I just want to know if somebody has done anything like that and how much success has been achieved.

Re: Turbulent non-Newtonian fluid flow using k-w model
 
I have sucessfully implemented Wilcox (1998) k-w with newtonian fluid but having lots of problems with NN flow. Has anyone been able to overcome the shortcoming of CFX4.2 of implementing low reynolds number model with NN fluid flow??? Please reply soon. Regards Athar
