- Аннотация: The results of a numerical and experimental investigation of the thrust and gas pressure pulsations on the thrust wall surface in annular and linear dual slotted nozzles are presented under the laminar flow conditions. The experiments are carried out in a pulsed aerodynamic setup using the products of combustion of acetylene-air mixture as the working body. The calculations are performed on the basis of Navier—Stokes equations for a multicomponent reacting gas medium using a chemically-nonequilibrium thermochemical model. The calculated and measured spectral compositions of the pulsating gas pressure at the center of the thrust wall of the annular nozzle are compared. The dependences of the pressure pulsation frequency and amplitude at the thrust wall center and the thrust on the gas pressures at the nozzle entry and exit, the dimensions of its critical section, and the deflector shape are established.
