i want to simulate a model containing vaporization and condensation .Ammonia(NH3) is filled in a cylindrical pipe. Liquid ammonia(NH3) is heated to vapor at the lower part of the pipe .The vapor transports to the upper part of the pipe and changes to liquid because of the low temperature of the upper part of the pipe.Then the liquid transports to the lower part pipe along the interior pipe wall. Can you give me some advise???Thank you very very much!!

Supposed that you employ VOF multiphase model, you need to add a mass/heat source term between phases with an udf. You can find a simple one in the udf manual.
Hope this helps Edi. |
