Hi Cfd members,
Ive been working on a simple 2d model with a condenser of AC system. I've kept material inside the tube as steam at 400K from input and by heat transfer from surrounding walls of tube at constant 320K, the water vapor condenses and finally output has a mixture of 100%water liquid. The problem after simulation is that the phase change occurs right on front of ouput boundary...and not in between condenser...I varied the velocity; yet phase change was observed very close to output wall. The whole condenser carried steam even when heat transfer was enables via coupled walls from environment. Is it because of output pressure having value zero? Tnx in advance. |
