![]() Continued advancement in computing has resulted in equally advanced and accurate evaluation of flow regimes using CFD software. With the continuation of these trends it became economical to study fluid flow, bringing forth the advent of computational fluid dynamics. On the other hand, as this trend increased, the cost of developing such systems decreased equally fast with each development. ![]() Fortunate enough, it is during this period that recorded exponential increase in the computing capabilities and growth of programming languages necessary to program foundational mathematics. A few years ago, only a few institutions of learning were in possession of funds adequate to construct and operate viable tunnels capable of being utilized in learning activities. This helps in obtaining the aerodynamic forces and pressure distribution measurements as well as investigate the fluid flow behavior. A wind tunnel operates on the principle of artificially producing airflow past a stationary body to simulate the actual conditions acting on the model. For simple aerodynamic experiments for demonstration purpose it would be uneconomical to buy or lease such wind tunnels. This is associated with complexities and large expenses. Keywords: Aerofoil, NACA, Flaps, Wind Tunnel Testing, Composite material.Īerodynamics research and model testing are mostly done on large wind tunnels for industrial research. So we make use of the composite material carbon-carbon to replace the wing material for the aircraft. Composite materials are the most advanced materials which have a longer life and performance characteristics than other materials. The NACA24012 aerofoil series finds application in general aviation, piston powered bombers, transport, commuter and business jets. Two component balances is used to determine the wing parameters. The control surfaces attached with the wing are flaps, trim tabs and they are actuated using servo. This aerofoil has low pitching moment and has little roughness effect. This aerofoil has high coefficient of lift than other airfoils. Cambered wing with NACA24012 aerofoil series has been chosen for the estimation. The main aim of our project is to estimate the wing parameters such as lift, drag, coefficient of lift, coefficient of drag, stall point for varying angle of attack and to visualize the flow using low speed wind tunnel. Comparisons of the CFD results with numerical predictions from the XFOIL result and NACA report showed a good agreement. The main focus of this investigation is to analyze the flow behavior around the airfoil body and to calculate the performance coefficients at velocity 10.5 m/s and angle of attack from 0° to 20°. In this paper, a review of aerodynamics of the two dimensional NACA 0015 airfoil for vertical axis wind turbine (VAWT) is attempted. The design and analysis of blades is one of the critical areas of wind turbine design. A blade's aerodynamic efficiency is expressed in terms of its lift-to-drag ratio. In this paper, Computational Fluid Dynamics (CFD) is used to predict the aerodynamic efficiency of wind turbine blades. ![]() Energy extraction from wind energy is rapidly competitive to power production from other sources like coal. Wind energy is the most viable sources of renewable energy and it is environmentally friendly alternative energy sources. Continuous rise of energy demand and need for cleaner environment emphasizes efficient conversion of energy from renewable sources.
