Please help me completing the pre-processing step for this case.
water vapor and water flow in a pipe
using constant propertity or using IAPWS Equation of State? and using Thermal Phase Change,how to define Saturation Temperature? thanks in advance!!! |

Dear All,
I am trying to simulate a pipe condense flow. I chose water vapor at 100 C and Water at 25 C as fluids. in domain,water vapour as disperesed phase and water as contiunou phase.I set heat transfer as thermal energy,and in fluid pair model ,using thermal phase change model,set saturation temp to 100C. In inlet I set volume fraction of Water at 25 C to 0.5 and water vapor at 100 C to 0.5. uniform velocity is applied to the inlet. outlet is assigbed to be a pressure outlet boundary condition. Every looks fine. But an error appears Does anyone know the reason and advise me how to correct it? Many thanks. |
