Hi,
I'm working on micro nozzle (throat 20 um). similar to Eshan Roohi's Test Case (DOI:10.1007/s10404-010-0671-7). I need to setup with pressure difference. So I modified the Freestream.C to set the specified numberdensity values according to pressure(In and Out). I'm getting a weard result, it looks unphysical solution (Even though it is subsonic at throat, diverging section still accelarates). Usually the sonic line will be little down stream of the throat in micro nozzle case. But for me at the exit of the nozzle it gets around 0.8- 0.9. So can any one help me to sort this problem. I can post my problem setup also, If someone like to review it. Thank you ~Vignesh~ Last edited by Vigneshramaero; May 18, 2015 at 09:55. Reason: some mis spelled |
