Hey,

i would like to model a plate heat exchanger. A single plate is desired, surrounded by a hot and a cold fluid.
Now my question is:
What are some practical recommendations regarding the mesh as well as the boundary conditions? How do parameters like hydraulic diameter or turbulent intesitiy and length scale/mixing length behave?

For clearance i use GMSH for meshing and OpenFoam for solving.

Any shared experiences are greatly appreciated! Any discussion is welcome and i would love to hear from you!
