TLDR
In this paper, the use of stationary waterjet for the removal of coating material from the substrate is investigated analytically and experimentally, and the cleaning width as a function of standoff distance, water pressure, and nozzle radius is derived by considering the structure of waterjet and cleaning mechanism.Abstract:
The use of stationary waterjet for the removal of coating material from the substrate is investigated analytically and experimentally. In the analysis, the cleaning width as a function of standoff distance, water pressure, and nozzle radius is derived by considering the structure of waterjet and the cleaning mechanism. Also derived are the relations of the optimal cleaning standoff distance and maximum cleaning width to the critical cleaning standoff distance, and how the water pressure and nozzle radius affect this critical standoff distance. These derived analytical relations are verified with experimental results.read more

Characteristics of abrasive slurry jet micro-machining: A comparison with abrasive air jet micro-machining
TL;DR: Abrasive slurry jet micro-machining (ASJM) uses a well-defined jet of abrasive slurry to erode features in a solid target as mentioned in this paper, which is the dominant material removal mechanism in both ASJM and AJM in spite of the significant flow-induced decrease in the local impact angles of many of the particles in ASJM.

Characteristics of abrasive waterjet generated surfaces and effects of cutting parameters and structure vibration
TL;DR: In this article, the authors used three-dimensional surface topography analysis for evaluating waterjet generated surfaces and found that the smooth zone has a random, moderately isotropic texture, with the height distribution nearly Gaussian.
