A Non‐Reciprocal Architected Porous Medium
ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow.

Jet noise : aeroacoustic distribution of a subsonic co-axial jet [PDF]
The noise generated by aircraft can be easily heard by those living under the flight path of passenger or cargo carriers. It is considered an environmental pollutant and is treated as such by the International Civil Aviation Organization (ICAO) who ...

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

On acceleration of jets by radiation pressure
Acceleration by radiation pressure could, in principle, explain the observed relativistic velocity of jets in extragalactic radio sources. The radiative aceleration mechanism is based on radiation beams that are produced and collimated in funnels (vortices) along the rotation axis of a thick accretion disk. These radiation beams accelerate particles to

High-pressure water jet injury to the chest
The high-pressure water jet cutting method, which uses a high-pressure water stream to cut hard materials, is widely used because it does not generate sparks or dust. However, once the high-pressure water jet is accidentally fired at a human body, a large amount of water containing abrasive materials flows into the body in a short time, causing ...
