Abstract :
Along with the progress of industry and technology, the need for diverse and single-purpose devices and equipments increases. In addition to this diversity, the different tastes of users and the trend towards the development of the industry have caused that other old production systems such as ordinary lathes are not able to respond to the continuous changes in market demands. In this research, the results related to different flow parameters, such as static pressure distribution and velocity distribution, in the water jet and its surroundings have been investigated and analyzed by changing different parameters. It has been tried to discuss the suitable area for cutting each of the water jet flow parameters on this area. The lower the turbulence of the flow, the better the cutting quality and the more uniform the speed output, and the lower the speed drop. Kinetic energy and turbulence intensity with the increase of particle diameter from 10x10-5 to 10x10-4 m at flow rate of 0.2kg/s decrease by 8.73% and 4.60% respectively and the intensity of corrosion and vertical pressure caused by particles They will increase by 737.20 and 334.45 percent, respectively.
