turbine 2 ?

amine

Hi

i'm doing a radial turbine simulation with the K_eps as a turbulence model ,the probleme is that my actual hardware is not as that,this is why i'm using 5 inflation layers to keep low the elements number ,is it enough to get accurate results,and my seconde question ,in which region i should use a small mesh?

the more important question is ,when i'm trying to get a good mesh ,how i should manage this process,it means ;starting from let us say any mesh ,how could i know the problem region and correct the mesh there?

expecting a response from Glenn

thanks
