Investigation of thrust vector angle control law based on micro-turbojet engine

open access: yesAIP Advances, 2022
The fluid thrust vectoring nozzle has a fixed profile, few moving parts, and lightweight structure, providing effective flight control for high maneuvering aircraft. The nonlinear control law of the jet deflection angle is one of the critical problems of

Design, Modeling and Simulation of a Liquid Jet Gyroscope Based on Electrochemical Transducers

open access: yesMicromachines, 2021
We propose a novel liquid jet gyroscope based on electrochemical transducers, which uses electrolyte as the jet medium, and two electrochemical transducers placed symmetrically as the velocity measuring unit.

A 1D fluid model of the Centaurus A jet [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2019
We implement a steady, one-dimensional flow model for the X-ray jet of Centaurus A in which entrainment of stellar mass loss is the primary cause of dissipation. Using over 260 ks of new and archival Chandra/ACIS data, we have constrained the temperature, density and pressure distributions of gas in the central regions of the host galaxy of Centaurus A,

Reynolds number dependence of scalar fluctuations in a high Schmidt number turbulent jet [PDF]

open access: yes, 1991
The scalar rms fluctuations in a turbulent jet were investigated experimentally, using high-resolution, laser-induced fluorescence techniques. The experiments were conducted in a high Schmidt number fluid (water), on the jet centerline, over a jet ...

Numerical Simulation of Entrainment by Jet Flow Characteristics in Spray Semi-dry Desulfurization Tower

open access: yes发电技术, 2018
The characteristics of entrainment by jet flow in the spray semi-dry flue gas desulphurization tower have an important influence on the mixing of the flue gas and the absorbent in the tower and the uniform distribution of the flow field.

Optimization of the taper angle of the jetter confuser used for reversible blast cleaning of propellers from corrosion

open access: yesВесці Нацыянальнай акадэміі навук Беларусі: Серыя фізіка-тэхнічных навук, 2021
It is shown that it is very effective to remove corrosion products from various surfaces, including the metal surface of the propeller, using the new technology of reverse-jet cleaning (RJC) developed by the authors.

Reynolds-number effects and anisotropy in transverse-jet mixing [PDF]

open access: yes, 2006
Experiments are described which measured concentration fields in liquid-phase strong transverse jets over the Reynolds-number range 1.0×10^3 ≤ Rej ≤ 20×10^3. Laser-induced-fluorescence measurements were made of the jet-fluid-concentration fields at a jet-

An experimental and CFD study of liquid jet injection into a partially baffled mixing vessel: a contribution to process safety by improving the quenching of runaway reactions [PDF]

open access: yes, 2008
Thermal runaway remains a problem in the process industries with poor or inadequate mixing contributing significantly to these incidents. An efficient way to quench such an uncontrolled chemical reaction is via the injection of a liquid jet containing a ...

Falling jets of particles in viscous fluids [PDF]

open access: yesPhysics of Fluids, 2009
We have investigated the time evolution of a jet of non-Brownian particles falling under the action of gravity in a viscous liquid at low Reynolds number. Different regimes have been observed depending on volume fraction and particle-to-jet diameter ratio.

Numerical Simulations of Bouncing Jets [PDF]

open access: yes, 2015
Bouncing jets are fascinating phenomenons occurring under certain conditions when a jet impinges on a free surface. This effect is observed when the fluid is Newtonian and the jet falls in a bath undergoing a solid motion.
