the exaust gaz from the muzzle of a gun!!

bruxellois4 · July 7, 2010, 18:15

Hi!

I have to simulate the exhaust gas from a muzzle of a gun
(Compressible, V = 1000m / s) I measured the pressure it's considered as my initial condition (inlet pressure) so no combustion

which solver do you propose!!

thanks a lot!

Hello bruxellois4,

I would recommend sonicFoam.

A list of the standard solvers is available here: www.openfoam.com/features/standard-solvers.php

Thanks m.nichols19!!

I see that is the most appropriate solver too

.

i have some diffuclties with blokmesh, have you any idea where can i find an free mesh program!!
