“…It could be concluded that the shear stress direction was the same as the flow direction, which caused the height increasing at the same direction as the flow. It agreed well with that obtained by Jafar et al (2015).…”

“…In this work, three wear regions were found (as shown in Fig. 6a), which was similar with above work (Gnanavelu 2010) and the (13 (Jafar et al 2015). However, unlike 90° impinging jet (Gnanavelu 2010), present work of 30° impinging jet had three unsymmetric wear regions that could nominated as stagnation region (zone 1), cutting transition region (zone 2) and wall jet region (zone 3).…”

This work carried out liquid-solid two-phase jet experiments and simulations to study the erosion behavior of 304 stainless steel at 30° impingement. The single-phase impinging jet was simulated using dense grid by one-way coupling of solid phase due to its dilute distribution. The simulation results agreed well with experiments. It was found that after impinging particle attrition occurred and particles became round with decreasing length-ratio and particle breakage occurred along the "long" direction. Both experiment and simulations found that the erosion generated on the sample could be divided into three regions that were nominated as stagnant region, cutting transition region and wall jet region. Most particle-wall impacts were found to occur in the cutting transition region and the wall jet region. In the cutting transition region, holes and lip-shaped hogbacks were generated in the same direction as the flow imping. In the wall jet region, furrows and grooves were generated. The averaged grooves depth tended to become constant with the progress of impinging and reach the steady state of erosion in the end. In addition, it was found that impinging effect increased erosion and anti-wear rate.

“…Plenty of these components are made of hard-brittle materials which are not suitable for traditional mechanical machining such as milling and grinding. Fluid jet carrying hard abrasives has been utilized for processing ceramics, quartz and silicon wafers owing to its low thermal effect and high flexibility [1,2]. Chen et al [3] utilized low-pressure abrasive flow in microgroove machining and numerically modeled the trajectory and erosion action of particles.…”

Fluid jet machining has been widely used in machining of hard-brittle materials. However, the diffusion of jet flow significantly affects the erosion capacity. Magnetorheological fluid has been considered to take the role of pure water for carrying abrasive particles, due to its better concentration when the external magnetic field is applied. The present investigation focuses on the flow characteristics of magnetorheological jet, which are involved in the basic aspects of erosion mechanism. Numerical models of excitation coil and jet flow field were established to investigate the fluid pressure distribution on the target surface and the trajectories of laden particles. Experiments were also conducted to verify the simulation results and evaluate the feasibility of MR jet on surface finishing. The results indicated that the utilization of high magnetic intensity can effectively improve the concentration of jet flow and the processing quality of workpiece surface.

“…The parameters (i.e., standoff distance, dwell time and pressure) were examined with three nozzles of different sizes that affect target material damage during piercing operations in borosilicate glass using AWJM process [33]. Haj Mohammad Jafar et al [34] have proposed erosion models for the brittle material during machining using abrasive slurry jet process. Gupta et al [35] have applied ANN to predict the geometrical characteristics, i.e., Ra, width of cut, depth of cut and taper during machining using AWJM process.…”

In this paper, semi-empirical models of the performance characteristics, i.e., material removal rate, average surface roughness, kerf top width and taper angle in abrasive water jet machining (AWJM) of AA6351 aluminum alloy are reported. These models are developed using the dimensional analysis based on Buckingham ∏ theorem, and the proposed models for the considered performance parameters are analyzed both qualitatively and quantitatively using experimental data. Likewise, artificial feed forward neural network has been attempted to predict the considered performance parameters of AWJM process. For this purpose, different numbers of neurons have been tried at the hidden layer to obtain the best neural network. The validity of semi-empirical models and artificial neural network is verified using the experimental results. Furthermore, software prototype graphical user interface (GUI) is developed which allows user to interact with the models to predict the considered performance characteristics. The GUI is tested and validated through the experimental results. The results proved the functional capability and effectiveness of the GUI in predicting the performance characteristics.
