Abrasive jet with a small amount of abrasive particles formed from a mixture consisting of water jet

Abrasive jet slotting mechanism and mechanical model to study in order to establish oil ( water ) wells abrasive jet slotting theory, as the technology continues to improve and the process parameters to provide theoretical support . Slotted underground rock formations require two different types of metals and materials to be cut , so this study for universal abrasive jet cutting is also instructive significance and reference value. Abrasive jet with a small amount of abrasive  synthetic diamond  from a mixture consisting of water jet , according to the abrasive particle size , and the mass and volume of low concentration, uniform distribution , water flow rate is high, the abrasive particles can be characterized flows together with the water can be regarded as sparse balance solid-liquid two-phase flow .  cutting tools  a continuous medium , in the establishment of a solid-liquid two-phase flow on the basis of the basic differential equations , obtained with the solid-liquid two-phase equivalent single -phase fluid of the basic equations. Which can be applied to single-phase fluid mechanics and  abrasive grinding  fluid flow method problem . This paper uses polar coordinates , time-average method to create turbulence equations . By order of comparative law , the equation reduces to the corresponding turbulent boundary layer equations , namely freedom of circular cross-section turbulence abrasive jet differential equations .
