The Thermal Boundary Condition for High Speed Seal Flow

Abstract

Earlier derived relationships for Couette flow with thermoviscous fluids are adapted to accommodate thermal resistances between the bounding surfaces and the ambient. Recognizing that these equations are approximate, correction coefficients are included; and the magnitudes of these are evaluated to make the approximate predictions agree with accurate numerical calculations. The correction coefficients are shown to lie close to unity over most of the range of expected operating conditions. The establishment of these convenient representations provides a basis for examining the interactions of thermoviscous films with more complex bearing and seal geometries.
