Performance Improvement of Wind Turbines Using Vortex Generators (VGs): A Review
Abstract: In the present scenario, increasing use of fossil fuels for mass energy production leads to increased CO2 emissions and can lead to climatic changes at global level. In order to reduce the emissions, a gradual shift towards renewable sources is going on. In India, 1.6% of total energy is produced by using WTG’s. Major source of energy depends on blade surface and shape. It also depends on air flow pattern. …

Comparative Computational Investigation of Aerofoil Performance with and without Vortex Generators
Abstract: AbstractAircraft with an efficient aerodynamic design is a major concern in current aerospace industries trends, but the flow separation has been playing a predominant role in the aircraft performance reduction and thereby affecting the aerodynamic efficiency. To overcome these problems, vortex generators (vortilon) are fixed on the upper surface of the wing. This paper focused on the aerodynamic performance analysis of available NACA-23012 aerofoil with and without Vortex Generators, for …

A Novel and Efficient Transmission System for Harnessing Hydrokinetic Power from Ocean Currents
Abstract: This paper presents the design principles of a novel power transmission system for an indigenous device known as a “Hydro Vortex Power Generator” that harnesses the power of vortices from low-velocity streams of water. The flow-induced motions of an elastically mounted cylinder that is free to oscillate in the crossflow direction are converted to electricity by the power generator. To convert the oscillations with non-uniform amplitude and frequency to uniform …

Simulation of Flow Vorticity and Instability Analysis in a Solid Rocket Motor
Abstract: Combustion instability is a major problem in most solid rocket motor (SRM) during its operation. More form of instability is generated due to several factors like coupling of combustion acoustic waves with flow dynamics, grain configuration, combustion chamber design, combustible mixture, etc. This type of flow turbulence is sustained in such system for long durations and leads to failure of the mission. In this paper, an effort has been made …

FLOATING OFFSHORE WIND TURBINE WITH CARDAN SUSPENSION
Abstract: This paper describes a new structural design for a vertical axis floating offshore wind turbine (FOWT). The wind turbine consists of bowl-shaped blades set arranged circularly around a vertical axis on which they rotate due to the wind effect. A cardan mechanism supports the set and maintains the wind turbine in horizontal position despite the wave movement. The proposed wind turbine increases the power generation by 10% for a maximum …

Investigation of the Hall and Nernst-Ettingshausen Effects in Diluted Magnetic Semiconductors
Abstract: This review explores the Hall and Nernst-Ettingshausen effects in various magnetic systems, including diluted magnetic semiconductors (DMS), topological insulators, superconductors, and novel composite materials. In DMS, the interplay of ferromagnetism and magnetic impurities introduces unique transport behaviors, particularly influencing the anomalous Hall effect (AHE) and thermomagnetic phenomena. We also examine the Nernst-Ettingshausen effect (NE) in topological insulators and superconductors, revealing the influence of band topology and vortex-like excitations. Special attention …

Development and Investigation of Minimum Power Non-contact Swirl Vane Gripper
Abstract: The Swirl vane gripper is a new non-contact gripper, which uses negative pressure created by the air swirling flow to create an upward lifting force. This upward force can be used to lift an object, which is placed underneath the gripper. In comparison with other non-contact grippers, this gripper is electrically actuated (rather than pneumatically) and hence require less power to generate same lifting force as produced by other grippers. …
