Abstract : The thickness of a shock wave varies in direct proportion to its intensity and depends strongly on the density, molecular structure, thermal conductivity, and viscosity of the fluid. It is shown that by considering the thickness of a shock wave, in a calculation of the interaction of a weak wave with the boundary layer use may be made of the usual equations and methods of Prandtl's theory for the boundary layer. It is also shown that by considering the viscosity, certain problems (such as the interaction of a weak wave with a sonic line) can be solved in which physically impracticable characteristics and modifications would otherwise arise.
