Small Scale Horizontal Axis Wind Turbine
Abstract: In this work, the performance analysis of a designed small scale horizontal axis wind turbine (HAWT) has been presented and optimized by varying span length and chord length. The HAWT blades are shaped to generate maximum power from the wind at minimum cost. The blades are designed by using QBlade software and simulated in blade element method (BEM).The values of tip speed ratio and power coefficient have been obtained as …

A Review on Design and Flow Analysis of Quadcopter Propellers
Abstract: The quadcopter is a complex system in which propeller blades, aerodynamics, and structural behavior are tightly interlinked. Changing a small detail, such as blade angle or material, can significantly affect performance parameters like thrust and efficiency, as well as the drone's vibrations and stability in flight. Because quadcopters typically operate at Reynolds numbers between roughly 20,000 and 150,000, propeller theories developed for full-scale aircraft often fail to translate directly, making …

Numerical Analysis of New Airfoils for Small Wind Turbine Blade
Abstract: Wind energy is the major renewable energy source available easily in abundance. It has become more popular than other renewable energy sources because of its compatible cost with conventional energy sources. The demand of small wind turbine in the market with a reliable, durable and more efficient technology is increasing. Blade is the key element of wind turbine. Performance of wind turbine blade mainly depends on its airfoil. In the …

Studies on Thick Aerofoils at Subsonic Speeds for a Civil Transport Wing
Abstract: Airfoils are the most important elements of an aircraft wing, having a chord length a camber and a thickness distribution. Traditionally, airfoils were being developed by empirical methods taking considerable support from wind tunnel testing. The ratio of lift to drag indicates the efficiency of an aerofoil. The purpose of this study is to adequately acquaint, as a first step, with a validated vertex lattice method code, the X-foil for …

Analyzing Cavitation in Marine Propeller: A Computational Approach with Consideration for Polymer Applications
Abstract: A major source of noise and blade damage in marine propellers is because of the phenomenon of hydrodynamic cavitation. The Computational Fluid Dynamics (CFD) analysis approach is employed for the prediction of the cavitating propeller’s performance characteristics under various conditions of operation with the advance coefficient (J) ranging from 0.55 to 0.91 and cavitation number (σ) in the range of 0.80 to 4.50. The numerical simulation is performed on INSEAN …

Biomimicry of Eucalyptus Leaf Design for Optimization and Fabrication of Airfoil
Abstract: Biomimicry is the practice of drawing inspiration from natural forms to solve engineering problems, which has become progressively popular for refining design efficiency and performance. This work discovers how biomimicry can be applied to airfoil design, precisely through the unique structure of Eucalyptus leaves, a concept rarely explored in airfoil profiling. The work presented here, focuses on enhancing airfoil designs by incorporating the intricate features of these leaves. The airfoil …

Experimental Investigation of Lift forNACA 2412 Airfoil without Internal Passage with NACA 2412 Airfoil with Internal Passage in a Subsonic Wind Tunnel
Abstract: Wind tunnel experiments were carried out in a subsonic wind tunnel in Fluid Mechanics Laboratory at MITCOE, Pune. The objective of this research was to compare the experimental coefficient of lift and drag for a NACA 2412 airfoil with that for NACA 2412 airfoil with internal passage. Both the airfoils were of same dimensions and profile. The chord length (c) was 100 mm and the span (b) was 100 mm. …
