Flow Simulation (CFD) and Shape Optimization of an Airfoil Design and Compare with Wind Tunnel Experiment Result

Project Description:

1. Airfoil: An airfoil is a body of such a shape that when it is placed in an airstream, it produces an aerodynamic force. This can be seen in the cross-section of wings, propeller blades, windmill blades, compressor, and turbine blades in a jet engine.
2. NACA Airfoil: The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA”. You can use NACA 0012 for your project.
3. CFD: Computational Fluid Dynamics (CFD) is the science of predicting fluid flow, heat and mass transfer, chemical reactions, and related phenomena using numerical methods. It produces a fairly accurate result with ease and convenience.

Project Implementation:

1. Perform wind tunnel analysis and record pressure head at different points by varying angle of attack and wind velocity in succession. Then from that calculate lift force, drag force and lift coefficient. Plot all the data vs Angle of attack.
2. Then perform CFD simulation using the Acusolve software. Do proper meshing in the boundary layer for a better result. With the help of Aerodynamic characteristic of the airfoil such as static and dynamic pressure, skin friction coefficient, wall shear stress, turbulence intensity in the transonic regime you need to analyze and predict the performance parameters of the airfoil such as lift coefficient, drag coefficient at a various angle of attack and wind speed.
3. By plotting various graphs such as Lift coefficient vs angle of attack, Drag coefficient vs angle of attack compares your CFD result with the experimental result for validating your numerical solution.

Software Requirements:

1. Acusolve: You will be needing Acusolve software to perform CFD simulation and visualization of the result.
2. Miniplot: Also, you need plotting software such as Miniplot or Uniplot to plot the result data and compare the results.
