 May 22, 2004, 11:50 high mach number #1 Arthur Gamara Guest   Posts: n/a Dear cfd guys and girls, i need to set my Fluent 5.3 for simulate high Mach number, so that i can see shockwave, can you people teach me how to set it??

 May 24, 2004, 00:40 Re: high mach number #2 krishna Guest   Posts: n/a Dear Arthur, I think it will be easy if r able to convert the Mach Number in terms of Velocity in m/s so that you can specify the velocity itself, I am not so familiar with 5.3 version, this is one of the option. krishna.

DO NOT SAY THAT AGAIN !!!!!!!! firstly to see shocks, study the flow around a simple curved object, or the flow in a converging nozzle. better do the first one. Far away from the foil apply FAR-FIELD BOUNDARY CONDITIONS with 101325 pressure, Mach=1.8 Set OPERATING CONDITIONS TO 0 from 101325 and run inviscid model. For the airfoil use no slip conditions (WALL).you will see the shocks. I am writing papers with Fluent on Hypersonic flow if you want anything contact good luck!
