Steam Condensation Inside a Pipe #2

Open nitinminocha opened 8 years ago

nitinminocha commented 8 years ago

Respected Sir Thanks for the wonderful solver. I am simulating condensation of steam inside a pipe of ID=10 mm, L= 0.3 m. The saturated steam (T= 412 K) is coming from the top at 1 m/s and condensed near the walls (T= 373 K). I tried both 2D and 3D simulations. 3D simulations not at all converge whereas 2D simulations showing weird results. The velocity increases to 6 m/s inside the domain and the condensation is happening non-uniformly at different places. I used Hilorelxed phase change model alongwith brackbill surface tension model. I am hereby attaching both 2D and 3D files. Please have a look and suggest me how to resolve this problem. Thank You condensation_image Sachin_2D.zip Sachin_3D.zip

Hello,

Please give me a little time, and I will take a look at the case.

Best wishes,

Alex
