I AM MSC. STUDENT & WORKING ON PROJECT "AERODYNAMIC ANALYSIS OF AIRFOIL NACA0012 USING CFD. I AM USING FLUENT TO FIND PRESSURE COEFICINT, LIFT & DRAG COEFFICIENTS AT VARIOUS ANGLES OF ATTACK AND AT DIFFERENT REYNOLDS NO.". I NEED EXPERIMENTAL DATA FOR VALIDATION OF MY RESULTS. I WILL BE THANKFUL IF ANY BODY SEND ME REQ. DATA.MY POSTAL ADDRESS IS; WAQAR MAHBOOB C-230,PIEAS HOSTELS P.O NILORE, ISLAMABAD PAKISTAN.

I am sure that people from NASA should be able to answer your question. In old days, NACA airfoil data were obtained experimentally. There was also a paper-back book on wing sections. Although I don't have the answer you need, I still think that what you are doing is an excellant idea. But, I'd like to go a step further, that is to be able to define the problem, obtain the solution, ( in this case by varying the angle of attack through the stall zone, and the Reynolds number ) without see the experimental data first. You may want to obtain solutions under different numerical schemes, different turbulence models. I can guarantee that you will learn a lot in this way. Seeing the experimental results before performing CFD analysis could be very dangerous to your work. Once you have the test data, it's too easy to make the CFD results match the data. In most cases, test data and CFD results are not reliable at all. So, once in your lifetime, please do a real favor for the people in the CFD community, that perform a serious CFD analysis, present the results, without seeing the test data at all. This is the only way for CFD to survive.
