I need a detailed guild about the use of wet steam model (only available multiphase model in density based) in simulation of condensation in a blowdown supersonic wind tunnel at Mach number 5. I attach the shape of the tunnel in a separated file.
Thanks
Dear Ramin,
my answer is not direct, but just for information sake...to get the transient temperature distribution during the beginning of the startup of steam turbines/power plant components (blowdown in your case), when condensation takes place, taking a very high value of heat transfer coefficient in convection analysis is standard practice. which is estimated from tests.
Just a comment. condensation in blow down tunnel is dependent on many factors like moisture content, air quality, length of channels. Its not an instantaneous phenomenon.
