i want to do transient analysis of convergent nozzle.
For boundary conditions:
Fluid : ideal air.
Inlet: subsonic and supersonic conditions, i know pressure at inlet,velocity also. for steady state analysis i want to vary pressure.
outlet: pressure ( I WANT TO SPECIFY- how to specify). relative pressure i take 0 bar
wall condition: no slip
turbulent model :K-Epsilon
for transient condition:
refering to Fluent tutorial:
how to specify time step
how do i proceed?
I tried with steady state specifying mass flowrate at inlet and pressure at exit but i is not converging.i think by boundary conditions are wrong...
please suggest me
