![]() ![]() But on the other hand, velocity decreases as the air passes through the bottom of the aerofoil and the pressure is increased. When the air passes over the aerofoil, velocity increases as the air continues to flow from its leading edge to the upper surface of the aerofoil and the pressure is decreased in that area. Bernoulli's principle states that an increase in speed must accompany any reduction in pressure and a speed decrease must accompany any pressure increase. The lift phenomenon can be explained by using Bernoullis equation. al., CFD Simulation of an Airfoil at different Angle of Attack, they concluded that lift and drag force also depend on the wing planform and on the wing Theoritical Analysis Later, lift and drag force was compared between these aerofoils to find out the suitable one.Īngle of attack changes. In this study, pressure distribution was analysed along with lift and drag force of two aerofoils (NACA 2412 and Boeingħ37) by varying angle of attack and velocity. Ovais Gulzar et.al., Impact of Variation in Angle of Attack on NACA 7420 Airfoil in Transonic Compressible Flow Using Spalart-Allmaras Turbulence Model, they observed that the 40 angle of attack has been found suitable as the pressure, velocity, mach number encountered are within safe limits for an subsonic flow. Fouad Kandil et.al., Performance of GOE-387 Airfoil Using CFD, they observed that the magnitude of the aerodynamic moment remains nearly constant when the area. Safayet Hossain et.al., A COMPARATIVE FLOW ANALYSIS OF NACA 6409ĪND NACA 4412, They investigate that the NACA 4412 is better than NACA 6409 in terms of less wake generation and less negative pressure on the upper surface of the aerofoil for same angle of attack. al., Boeing 737-700NG Airplane Flow Simulation, they demonstrate the aerodynamic characteristics of the aircraft. al., Evaluation of the turbulence models for the simulation of the flow over a National Advisory Committee for Aeronautics (NACA) 0012 airfoil, they observed that the computational grid split in two regions, a laminar and a turbulent region. al., Research on Flows for NACA 2412 Airfoil using Computational Fluid Dynamics Method, they observed that the velocity magnitude for compressible flow was much higher compared to incompressible flow. al., A Comparative CFD analysis of NACA 0012 and NACA 4412 airfoils, they had investigated that 70 angle of attack is the optimum value for NACA 0012 and 60 angle of attack is the optimum value for NACA 4412. ANSYS Mechanical finite element analysis software is used to simulate computer models of structures, electronics, or machine components for analyzing strength, toughness, elasticity, temperature distribution, electromagnetism, fluid flow, turbulence, industrial machineries, explicit dynamics and other attributes. ANSYS is vast computational software that enables researchers to analyze the problems related to different engineering sectors. Computational fluid dynamics provides a qualitative and sometimes even quantitative prediction of fluid flow by means of mathematical modeling, numerical method and software tools. Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and data structures to analyze and solve problems that involve fluid flows. The flow of air over the aerofoils is the most important thing that has to be considered during designing an aircraft, missile, sport vehicles or any other aerodynamic objects. It is primarily concern with the forces of drag and lift, which are caused by air passing over and around solid bodies. Keywords NACA 2412, Boeing 737, CFD, ANSYS.Īerodynamics is the study of how air interacts with moving bodies. The whole analysis is solely based on the principle of finite element method and computational fluid dynamics (CFD). From this result, we compared the better aerofoil between these two aerofoils. ![]() The pressure distribution as well as change in lift and drag force of these two aerofoils were visualized and compared. The outcome of this investigation was shown and computed by using ANSYS workbench 19.0. By varying angle of attack, change in drag force and lift force were also analyzed.
