The accuracy of using a constant convective heat transfer coefficient of the flow field in conjugate heat transfer problems over various surface temperatures and geometries is numerically investigated. The complexity of analytical solutions as well as the acute computational cost necessitates decoupling the solid–gas interactions. The utilization of decoupled equations demands the convective heat transfer coefficient of the flow field to be independent of the surface temperature. The investigation is carried out over a number of conventional flow geometries as the laminar and turbulent flows over the flat plate, the turbulent flow behind a backward-facing step, and the laminar flow over the blunt nose in different Mach numbers. The results demonstrate that the convective heat transfer coefficient is substantially influenced by the surface temperature of the flat plate case at supersonic flows yet is barely affected by the surface temperature of the blunt nose case at subsonic flows.
It is illustrated that the validation of the decoupling approach should be questioned in different flow geometries to guarantee the accuracy of simulations in practical applications.
