Turbulent nonNewtonian fluid flow using kw model
Hi ! I am working on the implementation of 1998 kw model for the turbulent nonNewtonian flow. As CFX42 doesn`t allow to solve shear rate dependent viscosity with nonNewtonian 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 nonNewtonian fluid flow using kw model
I have sucessfully implemented Wilcox (1998) kw 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
