Flow Dynamics and Acoustics of the Gas Jet Emanating From a Conical Nozzle Into an Immersed Space

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

The subsonic and supersonic gas jets emanating from a conical nozzle into an immersed space were investigated. The influence of the difference between the total pressure at the inlet of the nozzle and the static pressure in the surrounding medium on the structure of such a jet and its flow dynamics and acoustics were determined and the noise level in the far field of the jet was calculated. The results of numerical simulation of the outflow of a gas from a conical nozzle into an immersed space were compared with the corresponding experimental and calculation data available in the literature. The methods developed for numerical simulation of the flow dynamics and acoustics of gas jets can be used for solving different research and engineering problems as well as for development of new computational algorithms.
