Temperature Measurement during Abrasive Water Jet Machining (AWJM). [PDF]
Materials (Basel), 2022 This study was undertaken to look for confirmation that heat transfer induced by abrasive water jet machining (AWJM) affects the microstructure of the material cut. The structure of S235JR carbon steel used in the experiments was reported to change locally in the jet impact zone due to the high concentration of energy generated during cutting with the ...

Notes on the Abrasive Water Jet (AWJ) Machining. [PDF]
Materials (Basel), 2021 The aim of the research was to investigate changes of abrasive grains on metals observing the kerf walls produced by the Abrasive Water Jet (AWJ). The microscopy observations of the sidewalls of kerfs cut by the AWJ in several metal materials with an identical thickness of 10 mm are presented.

Multiphase Jet Flow in Abrasive Water Jet Cutting [PDF]
PAMM, 2009 AbstractA numerical model for ultra‐high velocity abrasive water jets (AWJ) is developed and jet dynamic characteristics are calculated under steady‐state, turbulent, compressible, multi‐phase flow conditions. The model is tested by comparison with analytical solutions for related theoretical problems, generally with very good agreement. Simulations of
