AN INTEGRAL METHOD FOR LAMINAR BOUNDARY LAYER CALCULATIONS: MOMENTUM THICKNESS AND MASS TRANSFER WITH ZERO PRESSURE GRADIENT

Abstract

Work by Rott and Crabtree and by Hill is the basis of an integral method solution to the equation for the concentration of species in the binary mixture boundary layer. The principal result is a relatively simple integral relationship between wall concentrati n and surface mass transfer rate for arbitrary mass transfer distributions. Only the case of helium injection into an undissociated airstream, with zero pressure gradient, is treated in detail but the method can be applied to problems involving o her gases. The results agree quite well with exact similarity solutions and with numerical results for the problem of a solid leading edge followed by a porous region. Solution to the upstream-mass-transfer-problem is also obtained easily. (Author)
