How does one vary Mach number and dynamic pressure independently in a wind tunnel
Hello all,
I am newbie to fluid dynamics. How does one vary Mach number and dynamic pressure independently in a wind tunnel. i want to repeat the same in CFD. Thanks, Jane |

Pt = Total pressure P = Static pressure gamma = ratio of specific heats (1.4 for air) Mach = Mach number Change your static pressure, and you can adjust your total pressure & mach number semi-independantly of each other. If your doing this in a wind-tunnel, you obviously need a pressurised tunnel. Beware of Reynolds effects while doing this however. Matching compressibility effects with Reynolds effects on a scaled tunnel model is not possible*. *at least, not that I'm aware. |
