Dual Synthetic Jets Actuator and Its Applications—Part III: Impingement Flow Field and Cooling Characteristics of Vectoring Dual Synthetic Jets

Actuators, 2022
In order to understand the impingement flow field and cooling characteristics of vectoring dual synthetic jets (DSJ), an experimental investigation was performed to analyze the parameter effects.

Structures Produced by the Collision of Extragalactic Jets with Dense Clouds [PDF]

, 1999
We have investigated how several parameters can affect the results of a collision between an extragalactic jet and a dense, intergalactic cloud, through a series of hydrodynamic simulations.

Control of a Round Jet Intermittency and Transition to Turbulence by Means of an Annular Synthetic Jet

Actuators, 2021
This paper deals with active control of a continuous jet issuing from a long pipe nozzle by means of a concentrically placed annular synthetic jet. The experiments in air cover regimes of laminar, transitional, and turbulent main jet flows (Reynolds ...

Self-induced vibration of impinging synthetic jets

Journal of Fluid Science and Technology
While numerous studies have examined self-induced vibrations in jets, the focus has predominantly been on continuous jets. Reports on self-induced vibrations in synthetic jets, which are characterized by their excited-vibration frequencies, are limited ...

Tomographic Simulations of Accretion Disks in Cataclysmic Variables - Flickering and Wind [PDF]

, 2006
Both continuum and emission line flickering are phenomena directly associated with the mass accretion process. In this work we simulate accretion disk Doppler maps including the effects of winds and flickering flares.

Study on flow characteristics of a synthetic jet by using a vortex method

Nihon Kikai Gakkai ronbunshu, 2016
A synthetic jet is generated by an oscillating flow that a time-averaged mass flow is zero, unlike continuous jets. Synthetic jets have been used for various applications such as mixing enhancement and active controls. The present study investigated flow

Precessing jets from a moving source and bright X-ray filaments in galaxy clusters

, 2005
We present hydrodynamical calculations carried out with the 3D yguazu-a code of a precessing jet model, which interacts with a plane parallel wind. This scenario describes an extragalactic jet, in which the jet source is in motion with respect to the ...

Advancements in Synthetic Jet for Flow Control and Heat Transfer: A Comprehensive Review

Fluids
Synthetic jets, generated through the periodic suction and ejection of fluid without net mass addition, offer distinct benefits, such as compactness, ease of integration, and independence from external fluid sources.
