An attempt has been made to form a qualitative correlation between the nozzle shape and issuing jet shap茅. The following points can be made: 1. (i) The major requirement of a nozzle is the efficient conversion of potential energy to kinetic energy. This is best achieved by a sudden, ...
This paper discusses a review on nozzle wear in abrasive water jet machining application. Wear of the nozzle becomes a major problem since it may affect the water jet machining performance. Design, materials, and life of the nozzle give significance effect to the nozzle wear. There are various...
Recent detailed articles by Twarowski indicate that small quantities of phosphorus oxides and acids in the fuel-rich combustion products of H2 + phosphine (PH3) + air should significantly catalyze H, OH and O recombination kinetics during high-speed nozzle expansions -to reform H2O, release heat...
Water is mainly used to control dust exposure directly and is usually achieved by using nozzles to atomise the water into particles close in size to the dust. The nozzle type, position, and arrangement relative to the dust sources are critical to capture the dust effectively. Water misting in...
Some specific characteristics of hypersonic flight are discussed and the potential future research is analyzed, which considers actuator dynamics, aerodynamic/reaction-jet control, flexible effects and dynamics interaction. However, as an inseparable technology, guidance and control are more closely related,...

COVID-19 pandemic has recently had a dramatic impact on society. The understanding of the disease transmission is of high importance to limit its spread be
Analysis of turbulent underexpanded jets. I - Parabolized Navier-Stokes model, SCIPVIS A new computational model (SCIPVIS) is described which predicts the multiple-cell wave/shock structure in underexpanded or overexpanded turbulent jets. SCIPVIS solves the parabolized Navier-Stokes jet-mixing ...
An Endoscope Measuring Probe (EMP), composed of a camera with superior spatial resolution (1 pixel = 3.5 μm), was finally used for image acquisition at the discharge nozzle of a transparent pump. Thus, the authors were able to analyze the drop break-up phenomena at this static region of...
On the other hand, APS involves the utilization of a plasma torch comprising a cathode and a nozzle-shaped anode. This configuration generates an electric arc discharge through the ionization of a gas mixture, typically argon and hydrogen16,17,18. Within the plasma torch, the gas mixture is ...
