Abstract

It is well known that the inlet pressure of the abrasive water suspension has significant effect on the erosion characteristics of the inside surface in the nozzle. Abrasive particles moving with the flow causes severe wall shear, there by altering the nozzle diameter due to wear which in turn influences the jet kinetic energy. This will reflect on the life of the nozzle for effective machining. In consideration of this aspect, in the present work, the effect of inlet pressure on wall shear stress and jet kinetic energy is considered and analysed. It is found from the analysis that an increase in inlet pressure results in significant increase in the wall shear stress induced. Also an increase in inlet pressure results in proportional increase in the jet kinetic energy
