A Study of Annular Slurry Jet for Abrasive Waterjet Cutting
FUNDAMENTALS OF WET ABRASIVE BLASTING
Ways must be found to reduce or eliminate dust generated during surface preparation and wet abrasive blasting, as an alternative to dry blasting, can be an answer to the problem. The equipment available for wet abrasive blasting is reviewed, comparing various types as to their convenience, productivity, abrasive suitability and consumption, inhibitor mixing, and water pressure and volume required.
EFFECT OF NOZZLE LENGTH ON GAS ENTRAPMENT CHARACTERISTICS OF VERTICAL LIQUID JET
For a vertical plunging liquid jet system using nozzles which had various values of the length-to-diameter ratio Lm/Dn, characteristics such as the bubble penetration depth Z and the gas entrainment rate Qg were studied experimentally in an air-water system. When nozzles of an Lm/Dn ratio exceeding 15 were employed, the values of Z and Qg were confirmed to be almost independent of Lm/Dn. Empirical correlations for predicting Z and Qg are also presented.
