Revendra Kumar Deshmukh,  Ashutosh Dwivedi
Abrasive water jet (AWJ) machining has found to been a most promising candidate in the field of advance machining technology and have considerable distant advantages over other machining technologies such as no thermal consequence, high flexibility and machining versatility, and small cutting forces. In the recent decades, anomalous research has carried in the field of cutting material such brittle, ductile as well as composite material using water jet. But there are still various research gap in the field of AWJ machining.
In this paper computational model the nozzle design of the AWJ has been analyzed with two phase flow (liquid -solid) in detail using a control volume approach within ANSYS, such that the performance of AWJ machining can be optimized. Effect of various parameters such as convergence angle, jet diameter ratio, and operating pressure effect on pressure, velocity, turbulent intensity, skin friction of AWJ has been examined and on basis of characteristics optimized nozzle of AWJ has been proposed. Before optimization the validation of work has been done with the available literature and found that the obtained results are within acceptable limit. Moreover, a new design of nozzle has been proposed which yields better performance in cutting
Keywords- Jet diameter ratio, Nozzle convergence angle, skin friction, Turbulence Intensity
