ABSTRACT

This report presents a CFD study of two-dimensional 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 − ω turbulence model is considered. Results are obtained for a wide range of Mach numbers (2 to 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 at increased levels of wall temperature discontinuity and at increased Mach number.
