From last two decades, plant fiber reinforced polymer/polyester composites have been effectively used in structural and automotive applications. Researchers manufacturers are looking forward for an effective utilization of these composites. However, despite the outstanding properties terms load bearing capacity environmental sustainability fibers uptake limited due to its poor machinability cha...

As a part of the development of a new design process of close capture exhausts systems for machining devices, based on fluid flows modeling, an experimental apparatus was realised, which recreates a machining operation in experimentally controlled conditions. The properties of the obtained spray of solid particles were entirely characterised using Phase Doppler Anemometry (PDA), in order to be ...

many experimental studies have been conducted on development of the scour hole as a result of vertical jet impaction. research has shown that aeration of the nappe flow in the model is much weaker than that in the prototype. therefore, the influence of aeration on scour holes needs further study. experimental investigation of the effects of air entrainment and tail water depth on the scour hole...

The k-ω Shear Stress Transport (SST) turbulence model is adopted to study the hydrodynamic performance of the water-jet axial pump which is applied in Unmanned Surface Vehicle (USV). The numerical simulation of the whole passage of the water-jet pump is carried out for four different tip clearance with δ = 0.3 mm, δ = 0.8 mm, δ = 1 mm and δ = 1.4 mm. And the results, in term of external charact...

The efficiency and product quality of hydro-abrasive machining (HAM) could be considerably improved if the energy dissipation phenomenon of the jet-like tool during the material removal is clearly understood. An on-line technique for quantifying the amount of energy dissipated in the workpiece during HAM using acoustic emission (AE) measurements is presented in this paper. The measured AE-signa...
