OpenFOAM has two solvers (chtMultiRegionFoam and chtMultiRegionSimpleFoam )  for simulation of heat transfer across different materials.  When a solver has the keyword simple in it’s name in OpenFOAM, it means it uses SIMPLE algorithm for pressure-velocity decouple, Moreover, it represent it is an steady solver.

here, i mention two conjugate heat transfer problems i’ve done using these solvers:

  • transient heat transfer between two co-center pipes.
simulation of transient heat transfer between co-center pipe using chtMultiRegionFoam
  • air flow over heated obstacles are simulated based on Ref [1]. The velocity contour and solid temperature is shown blow
velocity and temperature contour for air flow over obstacles, simulation is done with chtMultiRegionSimpleFoam
