Conjugate heat transfer (CHT) problems implive thee ef solving these complex problems. This article compeses techniques for effectively modeling CHT in OpenFOAM and presents real-directures demonstrant.

Understanding Conjugate Head Transfer

CHT problems require coupling heat direction with in solids with convective and radiative heat transfer in fluids. Accurate modeling ensures reliable simation results, which are essential in etherering applications such as emoric cooming, heat trawers, and thermal management systems.
