Popis:	On the basis of a numerical and experimental investigation the pressure distributions are obtained along the walls of contracting and expanding flat symmetric nozzles having a section of constant, height in the region of the critical section. It is shown that a calculation in the approximation of two-dimensional flow of an ideal gas makes it possible to obtain basically reliable data. The flow is basically determined by the inviscid core of the flow, and the influence of the boundary layers is relatively small and manifested only at points of abrupt change of the pressure. The presence of a contracting part with straight walls and a section of constant height in the critical section gives rise to an appreciable disturbance of the flow at the start of the expanding part of the nozzle, but the disturbances are rapidly damped in the longitudinal direction.
