Implementation of the conjugate heat-transfer (CHT) analysis technique for hypersonic applications is the central theme of the present investigations. Understanding the applicability of the assumptions used in heat-transfer measurements and wall material-based flowfield analysis are the major objectives of the present studies. In view of this, a special CHT solver is developed for these investigations. This 2D-solver is based on explicit finite-volume formulation for fluid domain and implicit finite volume formulation for solid domain computations. The present numerical explorations are carried out using this in-house solver for various wall materials, different freestream Mach numbers, and freestream stagnation enthalpies of hypersonic flows over a finite thickness flat plate. Encouraging match has been observed between the results obtained from the CHT solver for very high thermal conductivity wall case and present fluid flow solver for isothermal flat plate case. Viability of assumptions used for post-processing the experimental data has also been proved. These results provide the evidence of usefulness of CHT studies for hypersonic applications. © 2013 American Society of Civil Engineers.
