Abstract : The laminar boundary layer flow with particles injected upstream of the leading edge of a plate is investigated. The boundary layer equations for the gas, and the equations governing the rate of momentum and heat transfer between the gas and the particles were solved simultaneously. A series solution is constructed in terms of a system of universal functions from which the solution for the arbitrary velocity and temperature ratio of the gas and the particles at the leading edge may be calculated. A closed form solution is obtained for the particle motion. It is found, within the validity of the approximation, that the wall shear force may be larger or smaller than that of the flow of clean gas, depending on the relative magnitude of the velocity of the particles and the gas at the leading edge; and that the wall heat transfer depends primarily on the relative magnitude of the temperature of the particles and the gas at the leading edge, and upon the wall temperature.
