one of the most common methods for controlling and increasing maneuverability of projectiles, especially the ones which move at high altitude and in low density air, is using lateral or reaction jets. the resultant force of the reaction jet is related to the jet and flow parameters. for finding their relation experimental, numerical, and analytical methods have been used. in order to change the...

Abstract Jet-Electrochemical machining (Jet-ECM) is a novel variation of traditional electrochemical in which electrically conductive material removed through anodic dissolution by means fine jet electrolyte. In this study, the effect nozzle geometry on removal characteristics are investigated physical experiments performed Jet-ECM system under development at university Manchester. A total 8 no...

Cold spraying is a coating process which enables production of metallic and metallic ceramic coatings with dense (very low porosity level) and pure (low oxygen content) structures. Several coating applications such as corrosion resistance and electrical conductivity rely on these properties. Generally, cold spraying is based on higher particle velocities and lower process temperatures than othe...

The paper presents a comprehensive numerical and experimental analysis of the Tesla turbine. turbine rotor had 5 discs with 160 mm in diameter inter-disc gap equal to 0.75 mm. nozzle apparatus consisted 4 diverging nozzles 2.85 height minimal cross-section. investigations were carried out on air subsonic flow regime for three pressure ratios: 1.4, 1.6 1.88. Maximal generated power was 126 W all...

Nozzle clogging is a serious productivity and quality problem in continuous casting. This work reviews the causes, effects, and solutions to clogging in continuous casting nozzles. The results of a one-dimensional, steady state analysis of the heat loss from the molten steel stream through the nozzle wall are discussed. The analyses show that steel may freeze within the clog matrix for a relati...

The yield of flow cytometric sorted Xand Y-chromosome-bearing sperm in a given time period is an important factor in the strategies used for fertilization and the production of sex-preselected offspring. This yield is dependent on the efficiency with which the modified flow cytometer/cell sorter analyzes the DNA of spermatozoa. The efficiency is directly related to the number of sperm with the ...
