The author's first monograph on turbulent jets, in 1936, dealt exclusively with a unfastened submerged jet. for the reason that that point, the idea of the turbulent jet has been constructed in lots of released works either within the USSR and out of the country: it's been enriched with a large number of experimental fabric and has been utilized in lots of new fields of engineering.In the final 10 years very titanic growth has been made, and it has now develop into attainable to move past the loose submerged jet and to resolve the matter of a jet in a circulation of fluid, take into consideration the interplay among the jet and good partitions, to envision the connection among the contour of the jet and the ratio of its density to the density of the encircling medium, and to set up the attribute good points of a supersonic jet.This monograph includes the result of additional learn by way of the writer and his colleagues, in addition to a serious reappraisal of the extra very important theoretical and experimental facts released by way of different investigators.The first part bargains with the idea of a turbulent jet of incompressible fluid. It provides a scientific research of various experimental facts on speed profiles, temperature, and the impurity focus, in addition to the outlines of the turbulent blending lone. the second one part units forth the idea of turbulent fuel jets, together with strongly preheated and supersonic jets. the idea of loose turbulence in a fuel, compatible in precept for any measure of compressibility, is revised, and the equations are derived for movement and warmth alternate within the boundary layer of a jet at very hot temperature. The 3rd part solves numerous difficulties of the spreading of jets in finite and semifinite area, and the fourth part describes a number of functions of the idea of jets, a lot of that are stated for the 1st time or were considerably revised.
