Aerofoil analysis

Hi All!

I am trying to optimise one axial flow pump with very low head.

Its a 360 deg steady state case. I have extended the size of rot domain 3 mm from leading edge and trailing edge sides. Rot domain meshed with tet and st with hex. Defined frozen rotor ggi between rot and stationary domain without any pitch change. So total geom looks like a pump in a pipe. Defined static pressure inlet with flow direction as zero gradient and turbulence also to zero gr in rot domain. Used SST in both domains with no HT. Initialisation is automatic.

Getting convergence But still no validation done coz it will require a prototype. but i dont know whether this rot domain size,Turbulence model is right to predict the phemomenon or should i try Transition model in rot dom and k-E in stationary dom? any thing missing ?

waiting for responses. thanks in advance.
