Development of a velocity fields and concentrations measurement procedure using PIV in flows which are typical for gas-turbine engines
Aerospace propulsion engineering
AbstractThe goal was the development of PIV technique (Particle image velocimetry) for examination of complex turbulent streams, which are typical gas flows for aircraft engines and gas-turbine installations. Comparisons between PIV data and LDA (Laser Doppler anemometry) were performed. Also phase-averaged velocity fields measuring procedure by means of PIV has been developed. Besides, the measuring procedure of fields of gaseous fuel concentration behind front module of combustion chamber with various types of injectors as a part of the front module has been developed. It is shown the possibility of use PIV technique in the experimental researches developing of perspective aviation engines and gas-turbine installations.
