 i m simulating the newtonian and non newtonian behaviour of the fluid in Ansys cfx solver.

how to specify non newtonian behaviour of the fluid domain and how to enter temperature and viscosity relation in the expression field.

can i have some tutorials regarding ccl and cel in cfx?

You set the model to Laminar. Then under Material Tab you to Transport Properties and you change it to "Non-Newtonian Model". CFX includes 7 Non-Newtonian laws.

If you want to use an expression: you need to refer to Temperature and Strain. Check the standard CFX tutorials like Mixing tube where a lot of expression have been used.
