Bench for purging models of gas-dynamic devices

Department of power plant thermogas dynamics

Head of department – D.Sc., Professor Hennadii O. Strelnykov


Purpose

  • Research of the flow structure using the Tepler shadow device
  • Research of the flow structure using soot-oil coating
  • Research of the flow parameters in the model by measuring the distribution of total and static pressure over the volume of the model
  • Research of the process of mixing gases in the injector heads using a digital gas analyzer
  • Research of the effect of a detonation wave on the supersonic gas flow

Components of the bench:

  • Compressor with receiver;
  • Pneumatic shut-off valve control;
  • Digital data collection system;
  • Video recording equipment;
  • Manometric shield for pressure measurement.
