Abstract : The compressible laminar boundary layer in a pressure gradient with suction, for a Prandtl number of unity and a linear viscosity-temperature relation, is analyzed on the basis of the momentum and thermal integral equations in conjunction with sixth and (for separation) seventh degree velocity, and seventh degree stagnation enthalpy profiles. For flows over a flat plate, and for flows in a pressure gradient, straightforward and simple methods of calculating the boundary layer for a given Mach number, a given uniform wall temperature, and a given suction distribution are shown. Wherever exact or purportedly accurate solutions for an impermeable or a permeable wall are available, the results obtained by the present analysis agree very well with such solutions, including the general asymptotic suction solutions for compressible flows with a pressure gradient and heat transfer. Finally, the boundary layer with a linearly diminishing external velocity is calculated. (Author)
