criterion for condensation??????
Hi all;
I am simulating the condensing water-vapor flow in a tube. Initially,fluid is single gas phase, but fluid is condensed,gradually . Is following criterion suitable and logical to distinguish liquid phase from gas phase? If T < Tsat , Fluid is in liquid phase zone.T > Tsat , Fluid is in gas phase zone. Reynolds number is about 100000. Best regards. |
Re: criterion for condensation??????
I think this sound suitable!!! And I think it has nothing to do with the Reynoldsnumber (exept from the heat transfer and the fow conditions which were responsable for the temperature value ;-) )

Re: criterion for condensation??????
I think what u said is okay only if pressure is included while calculting the Tsat.
Pressure plays major role in deciding the Tsat. [Ref. the chapter Pure Substances in any Basic Thermodynamics book ] If u have already taken care the pressure effect then the following is correct. If T < Tsat , Fluid is in liquid phase zone.T > Tsat , Fluid is in gas phase zone. All the best, MKP |

hi i am solving one heat pipe,nothing but a closed axialy rotating zone carying freon vapour.can u tell me wat are the solver settings necessary.
