Hi,

There could be several reasons why your results are not matching reality. Here are some common issues and suggestions to improve your simulation:

  1. The mesh near the boundaries and interfaces should be fine enough to resolve the boundary layers. If the mesh is too coarse, it may lead to inaccurate results.

  2. Ensure that the fluid inlet and outlet conditions are well-specified, and any external heat transfer conditions are accounted for accurately.

  3.  Verify that you are using the correct material properties for all the components involved (plate A, plate B, and fluid).

  4. Ensure that the solver settings are appropriate and converged. 

  5.  The heat transfer coefficient you mentioned can have a significant impact on the heat transfer rate between the solid and fluid. Ensure you have the correct coefficient and convection boundary conditions set up.Thank you.
