Heat Pipe Modelling
Hi,
I am trying to model a heat pipe with Fluent. i am using VOF and my two phases are water and vapor, at the beginning the vapor percentage is 0. Using laminar flow for nowand using pressure-velocity coupling- coupled with volume fraction, I get divergence detected in AMG solver: temperature. I don't know where exactly I should look for a solution to my problem. Any suggestions? |
Hi. Try to run a single phase flow without energy equation and see if that works. Can you post a picture of setup and mesh?

Hi,
Thanks for your reply, I tried that but I get reverse flow in pressure outlet and I can get convergence. I copied the geometry and mesh on the word file attached. I couldn't attach the actual file (was getting an error). Any help is appriciated. Thanks Nasim |
I don't understand your pictures. What is your domain and what means the last picture? I can't find any geometry that looks like that in the pictures before.
Nevertheless your mesh looks much too coarse (without knowing what you actually do). |

Hi
I want to model micro heat pipe flat grooves (or micro fins) rectangular would mesh with ICEM, but due to the small diameter of the semi-circular groove about 0.4 -1 mm and a width of 60 mm, height of 3 mm and is length 930mm. First question, how to generate mesh with the this program The second question, I want to UDF micro heat pipe flat for phase change in Fluent Yours truly Kaveh Shojaei...... |
