Heat through a wall.

Juan Martin Catelén

Hy! I'm trying to model a pool with water entering at one temperature and going out at a lower temperature. The pool is loosing energy through the walls and mainly by the surface where I fixed the heat flux. I'm getting a huge transfer coefficient and almost a constant temperature in the vertical direction. I imagine it´s because of the model I used (k-E) and the mesh I had. I'm using now k-w model. Will this fix the problem? What should I do when I want to calculate the heat through a wall? Bye. I'll be waiting for answers.
