Two-dimensional thermal boundary layer corrections for convective heat flux gauges

This work presents a computational fluid dynamics study of 2-D thermal boundary layer correction factors for convective heat flux gauges mounted in flat plate subjected to a surface temperature discontinuity with variable properties taken into account. A two-equation k-omega turbulence model is considered. Results are obtained for a wide range of Mach numbers (1-5), gauge radius ratio, and wall temperature discontinuity. Comparisons are made for correction factors with constant properties and variable properties. It is shown that the variable-property effects on the heat flux correction factors become significant.
