- Аннотация: Complex results in experimental and numerical flow dynamics and spectra of thrust force and gas pressure pulsations signals researches in annular and linear dual slotted nozzles are presented. Experiments were performed in a pulsed aerodynamic setup using the combustion products of acetylene-air mixture as working gas. Calculations of viscous flow are based on the Navier-Stokes equations for multicomponent reactive gaseous medium using a single-temperature chemical nonequilibrium model. Data of comparison calculated and measured spectral structure of pulsing pressure signals are presented. As a result, the dependences of frequency and amplitude of pressure, thrust force and flow parameters in annular and linear dual slotted nozzles from the throat and the deflector form sizes are established.
