Enhancing bladeless wind turbine performance using rear plates and diffusers through numerical fluid dynamics analysis

Discover Mechanical Engineering
This study develops a novel Bladeless Wind Turbine (BWT) concept that augments a 2D oscillating cylinder (diameter $${D}_{c}$$ ) with a rear plate and a diffuser assembly (inlet shroud, straight diffuser section, and flat flange), with and without a ...

Exact solutions of plasma flow on a rigid oscillating plate under the effect of an external non-uniform electric field

Results in Physics, 2020
The paper is concerned with the flow behavior of a helium-plasma bounded by a rigid, oscillating flat plate. The influences of an unsteady nonlinear external electric field (NEEF) on the plasma fluid were investigated.

Penetration Characteristics of Air, Carbon Dioxide and Helium Transverse Sonic Jets in Mach 5 Cross Flow

Sensors, 2014
An experimental investigation of sonic air, CO2 and Helium transverse jets in Mach 5 cross flow was carried out over a flat plate. The jet to freestream momentum flux ratio, J, was kept the same for all gases.

Development of an assistive instrument for lifting motion using driving springs

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017
To assist in lifting heavy weight objects from the floor, an assistive instrument that can be worn on the hip and knee joints has been developed. The instrument was driven by coil and flat spiral springs to operate for a long time.
