CALCULATION OF THE FLOW-INDUCED BY INJECTING GAS THROUGH THE WALLS OFA CHANNEL OF FINITE-LENGTH

A method is proposed for calculating the flow of a gas in a narrow pla nar channel of finite length. The gas is injected through the channel walls and effuses into the surrounding medium at a specified pressure. The calculations are carried out in the Prandtl approximation. A spec ial feature of the method being proposed is the possibility of determi ning the flow characteristics for various values of the characteristic Mach number on the basis of the results of a single calculation carri ed out at a fixed Reynolds number. The procedure for taking account of the ellipticity of the problem being considered is considerably simpl ified.
