Fluid flow emerges with high velocity referred as liquid jet. Water Jet having its applications in many fields includes agriculture and power generation it has been widely utilized. Impact value of the jet is highly important, to generate maximum efficiency operation. Many factors influence impact depends on type vane used such as: Flat, hemispherical, curved etc. The aim this work investigate ...

This study presents effects of the vane spring stiffness on frictional power characteristics of a refrigeration compressor. Comparisons on the compressor performance are investigated for different vane spring stiffnesses with compressors designed with high and low shell pressures. Results show that while compressors with a low shell pressure using a higher spring stiffness combination may reduc...

the shape of a submerged vane is a major factor in the design of a vane system and affects the performance and secondary currents generated by the vanes. this study investigated the effect of five vane shapes on bed sediment processes (local scour at the leading edge and transverse distribution of sediment downstream of the vanes) at four flow intensities for a total of 20 experiments. the resu...

Supersonic separation technology is a new natural gas sweetening method for the treatment of with high CO2 (carbon dioxide) content. The structures Laval nozzle and supersonic separator were designed, mathematical models condensation swirling CO2-CH4 mixture established. characteristics in condensed droplets under different inlet pressures studied. results show that higher pressure larger dropl...

The reason for the abnormal wear between the vane-slot and the vane in the rotary compressor is analyzed in this paper. Firstly, the influence of lubrication at the clearance, the machining equipment accuracy and oil circulation (oil flow rate) is analyzed. Then the material characteristics including the hardness of the vane and vane-slot, the surface treatment of the vane and the deformation o...

The effects of the diffuser vane on the performances of the multistage centrifugal pump were investigated experimentally, taking account of the interactions among the diffuser vane, the return vane, and the next stage impeller. It is very important to match well the diffuser vane with the return vane, for improving the hydraulic efficiency of the pump. The efficiency may be more improved by mak...

Globally faster consumption of hydrocarbon fuel in the transport sector is posing threat to environmental and ecological imbalances and thereby depletion of hydro-carbon fuel is causing another challenge to oil reserves. In view of these issues extensive researches are being carried out to explore the alternative energy source and or to find out appropriate energy conversion system. The atmosph...
