Cleaning and Cutting with Self-resonating Pulsed Water Jets
نویسندگان
چکیده
A new type of pulsed water jet, which uses principles of self-resonance to create pressure fluctuations, is now being developed. The advantages of pulsing to improve the erosive action of a jet—by interrupting the flow, hence using the water hammer impact stress created by each individual slug—have long been appreciated by the users of water jets for cutting and cleaning applications. Of several self-resonating pulsed jet, or ''SERVOJET”, concepts, a design incorporating a Helmholtz resonating chamber, tuned to drive an organ-pipe segment, has proven feasible for in-air interruption of a water jet. Experimental results for several cleaning and cutting applications are described.

Using an experimental drilling simulator to study operational parameters in drilled-cutting transport efficiency
Inadequate hole cleaning can lead to many problems in horizontal and directional wells. In this work, we tried to investigate the cutting transport phenomenon by an experimental directional drilling simulator, considering the differences between the operational and experimental conditions. The inclination, fluid type (water, foam, viscous, and dense), rotary speed (0 and 110 rpm), nozzle bit si...

High pressure water jets are increasingly being used for cleaning surfaces on an industrial basis. In many instances the use of high pressure water, in such applications as car cleaning, is carried out in combination with mechanical brushes. However, there are many instances, particularly in self service units and where large industrial vehicles, which do not fit into a standard carwash, are cl...

This paper describes results of a factorial experiment on coal cutting at a traverse speed of 5 meters/min, with water jets at pressures between 500 and 2,000 atmospheres and nozzle diameters in the range from 0.5 to 1 mm. These results fill a gap in the existing results on coal cutting with water jets and form the basis for the design of a coal cutting machine. The interrelationship between pr...
