Surface mechanics design by cavitation peening
Although impacts at cavitation bubble collapses cause severe damage in hydraulic machineries, the cavitation impacts can be utilised for surface mechanics design such as introduction of compressive residual stress and/or improvement of fatigue strength ...

Caries Café: A Method for Consolidating and Co‐Constructing Knowledge of Caries
ABSTRACT Introduction Dental caries is multifaceted and requires dental undergraduates to receive training in underlying science, risk factors, disease prevention, and treatment. Caries content features at many different points in a Bachelor of Dental Surgery (BDS) programme, making it a large task to consolidate and assimilate in clinical practice ...

Development of Quince Peel Extract Loaded Chitosan/PVA‐Based Edible Films for Food Coating
ABSTRACT This study aimed to valorize quince peel (Cydonia oblonga Mill.) as an agro‐industrial by‐product by recovering phenolic compounds through ultrasound‐assisted extraction (UAE) and incorporating the optimized extract into chitosan/polyvinyl alcohol (PVA)‐based edible films.

Cavitation bubbles dynamics and cavitation erosion in water jet
A water jet test rig is used to the cavitation test of the brass samples. The single crater and the pits-group, are found on the specimen surfaces after 15 h test. A water jet cavitation model with the sound interaction among bubbles, is developed by applying a water pressure of water jet flow fields into the Keller-Miksis equation, so as to obtain the

Analysis of the Formation Mechanism of Secondary Tip Leakage Vortex (S-TLV) in an Axial Flow Pump
Studies on the tip leakage vortex (TLV) are extensive, while studies on the secondary tip leakage vortex (S-TLV) are rare. To advance the understanding of the formation mechanism of the S-TLV, turbulent cavitating flows were numerically investigated ...

Spray characteristics of a multi-hole injector for direct-injection gasoline engines [PDF]
The sprays from a high-pressure multi-hole nozzle injected into a constant-volume chamber have been visualized and quantified in terms of droplet velocity and diameter with a two-component phase Doppler anemometry (PDA) system at injection pressures up ...

Abstract This study evaluated experimental composites containing dicalcium phosphate dihydrate (DCPD) particles for toothbrush wear and roughness. Composites containing bisphenol‐A glycidyl dimethacrylate/triethylene glycol dimethacrylate with 50 vol% inorganic fraction consisting of barium glass and DCPD (35:15 and 15:35 vol%) or barium glass only ...
