pressure distribution in closed enclosure
 
hai, try to do this fluent for those using multiphas models. take an axisymmetric model of cylindrical tank. patch upper 20% with vapor and remaining will be liquid of any fluid like H2. then see the pressure before iterating, apply some heat flux on side wall and run...then for the very first iteration see the pressure..it will go into -ve values. bur for single phase fluid u wull find +ve values in pressure i hope some of u understand what i am saying please tell me what to do, any modification etc.

thanks Prasanth

I also have the same problem with my multiphase calculation. I have negative static pressure values at the wake regions.
