Identifying the processes and characterizing the pressure zone of water jet impacting on solid surface

open access: yesAdvances in Mechanical Engineering, 2022
The difficulty in understanding the flow characteristics of water jets impacting on solid surfaces made the water jet technology requiring further investigations. The Arbitrary Lagrange-Euler (ALE) method is used to develop a numerical model of the water
