Effect of molecular weight on mass-transfer cooling in a laminar boundary layer on a flat plate.
A discussion of a generalized presentation using available solutions of the laminar boundary layer equations for flow over a flat plate. Heat transfer results for several coolant gases may be presented as a function of mass-injection in such a form that a single curve results, which is valid for the range of Mach numbers and wall-to-free stream temperatures investigated to date. A similar representation is used for the local skin friction coefficient and the recovery factor. Certain relationships pertinent to the application of these results are included.
