Turbulent solid–liquid flow through the nozzle of premixed abrasive water jet cutting systems
A computational fluid dynamics analysis has been conducted for the steady state, turbulent, solid–liquid flow through nozzles used in premixed abrasive water jet cutting systems. The development of a theoretical approach to the evaluation of turbulent flow and particle dynamic properties in the nozzles is attractive because of the difficulties associated with direct measurements in nozzles of h...
متن کاملRole of Process Parameters on Pocket Milling with Abrasive Water Jet Machining Technique
Abrasive Water Jet Machining is an unconventional machining process well known for machining hard to cut materials. The primary research focus on the process was for through cutting and a very limited literature is available on pocket milling using AWJM. The present work is an attempt to use this process for milling applications considering a set of various process parameters. Four different in...
متن کاملAbrasive Water Jet Machining – The Review
Abrasive water jet machining (AWJM) is a relatively new machining technique. Abrasive Water Jet Machining is extensively used in many industrial applications. AWJM is a nonconventional machining process where material is removed by impact erosion of high pressure high velocity of water and entrained high velocity of grit abrasives on a work piece. There are so many process parameter affect qual...
متن کاملAbrasive Water Jet Machining - A Review on Current Development
Abrasive waterjet machining (AWJM) is one of the modern machining process for difficult to cut materials. It is an environment friendly and relatively inexpensive process with reasonably high material removal rate. In all the machining processes the quality of the work piece is depends on various design parameters. The process parameters which mainly affect the quality of cutting in AWJM are Hy...
متن کاملInvestigation on a Rock-breaking Drilling Mechanism by Using a High Pressure Jet Bit
How to effectively transfer and exert a pressure on drills in lateral drilling, and to raise the efficiency of rock-breaking and rate of penetration in a bid, is the key technology to improve the quality, speed and economic benefits of lateral drilling. Therefore, based on high pressure jet of 16-hole and 7-hole nozzles, which are suitable for lateral drilling in oilfield at the present stage, ...
