i am working on Mixed flow compressor my objective is carried out simulation of mixed flow compressor using fluent now available boundary condition is mass flow rate at inlet and pressure outlet the pressure at outlet is more than inlet every time i do simulation it first give reverse flow at outlet but after convergence it change the value of pressure at outlet i need this pressure constant plz give me some suggestion its urgent

hi,

at beginning u may get rev.flow sometimes. but slowly after convergence it wil be o.k. at compressors outlet the pressure is always higher than at the inlet. so wat u got is right.

I want basics of fluent.

search psu.edu site where u can get them
