SUBSONIC FLOW OF HOT GAS THROUGH A HIGHLY COOLED CONSTANT-AREA CHANNEL,
Abstract
Laminar flow of a hot viscous gas through a highly cooled, constant-area, semi-infinite channel is considered. An exact solution is obtained for the limit where the flow Mach number is low, the gas enthalpy at the wall is small compared with the centerline value, the Prandtl number is one, and the ideal gas equation of state is applicable. The resulting solution is one in which the pressure and axial mass flux is everywhere constant. For m = 0, the problem is equivalent to a heat conduction problem, and the solution for the flow throughout the tube is known. Numerical results are obtained for m not = 0 that describe the flow in the inlet region and in the fully developed flow region. In the latter region, the normalized velocity, enthalpy, and reciprocal density profiles are all identical and remain invariant with streamwise distance. The physical amplitudes of these quantities decrease in the streamwise direction as a result of wall shear and heat transfer. (Author)
