Impinging Performance of High-Pressure Water Jets Emitting from Different Nozzle Orifice Shapes

Geofluids, 2020
The impinging pressure of a water jet is a key factor in engineering applications, and the jet shape has a great influence on this pressure. In this paper, five different nozzle shapes were designed, and impacting tests were conducted based on a self ...

Evaluation of Influencing Factors in Cleaning Performance for Bio-Fouling Removal Based on High-Pressure Water Jets

Journal of Marine Science and Engineering
Regular inspections and hull cleanings are essential to prevent bio-fouling on ships. However, traditional cleaning methods such as brush cleaning and high-pressure water-jet cleaning at docks are ineffective in cleaning niche areas like bow thrusters ...

Research on flow field characteristic of close-coupled gas atomizing nozzles

Fenmo yejin jishu
The atomization nozzle is the core component for the metal powder preparation by close-coupled gas atomization method. The pressure at the tip of the melt delivery tube and the stagnation point is very important for the smooth outflow of the molten metal

Performance analysis of a rotating detonation combustor based on stagnation pressure measurements [PDF]

Combustion and Flame, 2020
Abstract This study explores the effect of differing inlet and outlet boundary conditions on the operation and performance of a rotating detonation combustor (RDC) over an annulus mass flux range of 50 to 210  kg s − 1 m − 2 and equivalence ratios of 0.7, 1.0, and 1.3.
