I am using fine/turbo to simulate a centrifugal pump. now i don't know what should be the best CFL number, and what's more, what should be imposed on the inlet and outlet conditions. A new comer thanks for your kind answer!

Inlet conditions :

Total pressure Total temprature inlet flow angle

Outlet condtions

static pressure

clf number depends on convrgee firt try to simulate on defualt condtions. if solution is stable and converging then increase it other wise decrese

Thank you!

the best CFL number that you can use is the 0.75 as it has given best results for me when I was doing the similar problem

thanks and regards BADRINATH

your problem is the incompressible case?

hello happy new year every one my english is so poor,genarary inlet boundary condition of steam turbine are all around the inlet ,now if we want to make partly inlet ,how to set in numeca ,i.e the degree is 0.5 thank you
