The paper is devoted to the study of deflector nozzles rain irrigation machines. selection parameters nozzle artificial sprinkler machines on a scientific and practical basis allows for correct organization ecologically safe irrigation. article presents results research short-distance with deflector.

The purpose of this study was to determine the effect variations in diameter and number nozzles on power efficiency Pelton turbine. research method is experimentally using a miniature turbine installation with 3 nozzles. Variations nozzle diameters 4 mm, 5 6 mm distance 80 90 100 rotation from 300 700 rpm. results showed that blade produced maximum efficiency, namely 30.00 watts 34.79%, respect...

We report a facile method to control intra-fiber porosity via varying the relative humidity and inter-fiber voids through the blending of two different polymeric fibers via multi-nozzles spinning of electrospun fibers for selective adsorption of oil from water.

Recent developments in the design of rotationally symmetric, convergingdiverging de Laval nozzles for the use in twin wire arc spraying processes are discussed. Various aspects of an efficient implementation of the proposed gas dynamics solution algorithm on modern multiand many-core architectures are addressed. Finally, a general framework for the application of massively parallel, derivative-...

We consider the behavior of a vibrating fluid cavity. Small nozzles are uniformly distributed in one direction on a side of the cavity. A theoretical and numerical study of the optimal control of the vibrations is done in order to obtain homogeneous fluid velocities at each nozzle.

Purpose. Improvement in durability of welded drums compressor rotors the gas turbine engines by treatment fluidized bed abrasive material.
