Nozzle Wear Parameter in Water jet machining The Review

Abrasive waterjet (AWJ) machining process utilized increasingly in industrial applications. It is a non- traditional machining process and involves complex mechanics. A nozzle is required to perform abrasive waterjet machining for material removal with the help of very high velocity of waterjet. The main problem of AWJ machining process is nozzle wear during the process. The wear depends on various parameters such as water jet characteristics, nozzle geometry, etc. The nozzle wear is not fully understood experimentally. Also the uncontrolled nozzle wear can affect the effectiveness and surface finish obtained through the AJM process. In this paper we propose to investigate and analyze in detail the nozzle wear (using ANSYS FLUENT). A comprehensive literature review for the proposed work is also being described. This analysis can be highly helpful for understanding nozzle wear during the AJM process.
