Experimental and numerical research of synthetic jet array

EPJ Web of Conferences, 2016
This paper describes the additional research of the synthetic jet array in a channel flow and continues the paper of authors Dančová, Trávníček and Vít, [1]. Numerical simulations support the experiments from [1] and the influence of the new slope of the

Effect of orifice shape on three-dimensional vortex structure of a synthetic jet

Nihon Kikai Gakkai ronbunshu, 2015
Synthetic jets are produced by periodic ejection and suction of fluid from an orifice induced by movement of a diaphragm inside a cavity, and a synthetic jet actuator is a useful tool for active flow control. The synthetic jet actuators are low operating

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Thermoacoustic cooling of loudspeaker-driven synthetic jet actuator

Case Studies in Thermal Engineering
To address the issue of declined cooling performance caused by the recirculation of hot jet flow into the cavity of conventional synthetic jet actuators, a loudspeaker-driven thermoacoustic-cooling synthetic jet actuator was developed by integrating a ...

Acoustic aspects of synthetic jet generated by acoustic actuator

Journal of Low Frequency Noise, Vibration and Active Control, 2018
Thermal overstressing as a result of miniaturization is the foremost challenge for the next generation electronic devices. Shrinking size of electronic devices makes this problem even worse.

Materials‐Driven Additive Manufacturing for Electrical Machines: Qualification‐Oriented Design Beyond Geometric Freedom

Advanced Engineering Materials, EarlyView.
This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...

Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

Experimental investigation of a control synthetic jet

EPJ Web of Conferences, 2012
Synthetic jets were used in previous studies to control a continuous round air jet. This study focuses on the single synthetic jet, which is measured using Constant Temperature Anemometry (CTA) and Particle Image Velocimetry (PIV).

Large-eddy Simulations on Flow Structures and Interaction Mechanism of Synthetic Jets in a Crossflow [PDF]

Journal of Applied Fluid Mechanics
The results of large-eddy simulations are presented to illustrate the flow structures generated by the interaction of synthetic jets with a crossflow. The coupled calculations involving the internal flow of the actuator cavity and the external flow are ...
