Experimental investigation of three-dimensional turbulent jets

Abstract

Detailed experimental data on alteration of dynamic characteristics of average flow characteristics depending on λ with the aim of generalization of the results in the extended area of λ value alteration. Replaceable nozzles are applied to form three dimensional streams. The nozzles with the extension λ=1; 2,66; 5,07; 7,61; 11; 16; 25,25 and a round nozzle have been applied in the experiments. The main changes have been arranged in the case of flowing velocity at the nozzle exit U₀ equal to 20 m/s and 40 m/s that is equivalent to the Reynolds figures 3,2 10⁴ and 6,5 10⁴ calculated on effective diameter.
