ANNOTATION The characteristics of the operation of turbines and jet nozzles on double-phase working fluids are examined in this book. By the method of successive approximations the flow of a doublephase flow, containing small particles, is examined with regard to the velocity and temperature lag of particles behind the gas; the results of computer calculations are presented, permitting a swift evaluation of the fundamental parameters of the exhaust of a doublephase flow from a nozzle. It is shown that the presence of a liquid undulating film on the wall of a nozzle leads to substantial losses in the boundary layer and causes a significant lowering of nozzle. efficiency. A method for evaluating turbines on double-phase flows with liquid particles is given in the book and the basic types of supplementary losses are examined: those due to impact of the liquid particles on the nozzle blade and as a result of friction on the undulating film covering the surface of the flow portion. In order to achieve a decrease in the losses due to particle impact on the blades, it is expedient to increase the axial clearance between the nozzle apparatus and the turbine wheel, at the same time lowering the erosional attrition of the rotor blades. In a birotative turbine the losses indicated above are essentially decreased and its effectiveness and reliability are maintained at a high level. A great amount of attention was given to the operation of a turbine on moist vapor and coal dust fuel. The book is intended for scientific and technical engineering workers in power machine construction and aviation industry. 12 Tables, 92 illustrations, bibliography, 72 citations.
