mep10jl is on a distinguished road
Hi, all

I am new to CFD, and new to ANSYS Fluent, hence, I need help to setup this simulation

I use GAMBIT to generate the mesh, and i set up the boundary condition as Velocity Inlet, Outflow, Wall, and Axis

in Fluent, i choose k-e as my turbulence model

How can i know the discharge coefficient? i know i need to know the pressure of 1d upstream, and 0.5d downstream, but what exact steps i need to step up this simulation

Can someone give some guideline how I can set up my simulaton correctly?

thx
