We compared the characteristics and polishing effect of abrasive suspension slurry jets with and without high polymer added. Results show that adding high polymer to the slurry jet leads to more concentrated jet beam and, consequently, surface roughness in the jet polished region is approximately equal and the interface between polished and unpolished regions is narrowed. We also examined the surface forming process polishing with slurry jet added with high polymer, and then proposed a polishing model of the process.

Abrasive jets can be used for polishing when fine slurry is used. This paper presents a model for the jet formation process, CFD simulations are carried out for the prediction of flow pattern in a nozzle with abrasive suspension slurry jets using the discrete phase model. The CFD model aids in understanding the process because of the difficulties in performing the direct measurement of the jet axial velocity and radial velocity, the model simulates the different pressure premixed slurry pass through the pipeline and the focus tube to the atmosphere. The model is able to predict the orifice eff

Abstract With high polymer added into suspension, the use of abrasive slurry jet (ASJ) has significant advantages in energy management. The quality and efficiency of ASJ are affected distinctly by its structure and the flow field feature, both of which depend on the rheological properties of the abrasive slurry. Therefore, this paper carries out a series of experiments to study the rheological properties of abrasive slurry with polyacrylamide (PAM) and carboxy methyl cellulose (CMC) commonly used in ASJ. The paper also explores the effect of temperature and abrasive on the apparent viscosity o

This paper presents a comparison between two types of abrasive liquid jet cutting systems: entrainment systems, which typically use abrasive-waterjets (AWJs) to perform the cutting; and systems that use directly pumped abrasive slurry jets (ASJs) to perform the cutting. The hardware features and the performance characteristics of the two types of systems are addressed. A simplified analysis indicates that at an abrasive-to-liquid ratio of 1:1, high-pressure directly pumped ASJs are twice as efficient as entrainment AWJs in transferring energy to the particles. Also, directly pumped ASJs are po

A slurry jet driller is a novel drilling method, which delivers an abrasive slurry and supercritical gas mixture, to an expander nozzle. The expanded fluids flowing out of the nozzle, energize the particles, which hit the target material and erode it, achieving drilling. The expansion of the gas from a super critical state to in situ pressure and temperature conditions is the driving mechanism of the drilling operation. The primary objective of this paper is to evaluate the feasibility of the novel slurry jet drilling system. An experimental program is carried out for testing the performance o

Polishing of a nominally flat aluminum substrate using a fluid jet, carrying abrasive particles, was investigated. The effects of jet orientation and polishing duration were studied, on a fixed spot on the aluminum substrate. Stylus profilometry was used to examine the final surface along different directions. It was seen that the final erosion contour is strongly dependent on the jet orientation. The surface roughness was found to be dependent on the slurry parameters. On average, the average roughness (Ra) of the aluminum surface was reduced from 430 nm to 139 nm. Best polishing was obtained

Solid particle laden flows are very common in many industries including oil and gas and mining. Repetitive impacts of the solid particles entrained in fluid flow can cause erosion damage in industrial equipment. Among the numerous factors which are known to affect the solid particle erosion rate, the particle impact speed and angle are the most important. It is widely accepted that the erosion rate of material is dependent on the particle speed by a power law Vn, where typically n = 2–3. Therefore, accurate measurements of abrasive particle impact speed and angle are very important in solid pa

Being capable in predicting the removal of material from a surface subjected to the impingements of solid particles within a carrier liquid is of considerable industrial interest. This phenomenon, called impact erosion, is of concern in many applications due to its severe technical and economic consequences. The use of Computational Fluid Dynamics (CFD) techniques for impact erosion prediction is a challenging approach to avoid the cost and complexity of laboratory testing. A well-established methodology exists for CFD-based erosion estimation, consisting in the simulation of the slurry flow b
