Influence of Non-Structural Parameters on Dual Parallel Jet Characteristics of Porous Nozzles
Micromachines, 2020 As an important actuator of the dual parallel jet, the porous nozzle has some non-structural parameters (such as inlet pressure, nozzle spacing ratio, etc.) which have a significant influence on energy transport, chemical combustion and pollutant ...

Investigating Vortex Ring Reconnection in Twin Parallel Pulsed Jets: Influence of Nozzle Spacing and Stroke Ratio [PDF]
, 2023 Even though interactions between pulsed jets showed great importance in biological fluid transport, they remain poorly described. An experimental piston/cylinder apparatus is designed to produce twin parallel pulsed jets. Using Particle Image Velocimetry

Dual-bell nozzle for space launchers with fluidic control of transition
AIAA Propulsion and Energy 2021 Forum, 2021 The dual-bell nozzle is a promising altitude adaptive nozzle concept for improving the performance of existing space launchers as well as future reusable launch vehicles. It is characterized by an inflection in the wall geometry which links a base nozzle with a nozzle extension. Two working modes are therefore attained: a low-altitude mode in which the

Effect of working pressure and spacing of nozzles on the quality of spraying distribution
Crop Protection, 2022 Abstract The correct placement of the crop protection product on the target depends on the adequate distribution provided by the spray nozzles. In this research, the objective was to verify the influence of the working pressure and spacing between nozzles on the quality of the spray distribution.
