Design and Analysis of NACA 4513 Airfoil

The equations for fluids are quite complex and can be difficult to solve especially if the geometry of a problem is intricate. To overcome such difficulties Computational Fluid Dynamics (CFD) has been constantly developed over the past few decades. A wooden modified Eppler-61 airfoil is fabricated with fifteen static pressure taps for measurement of surface pressure. The main objective of this investigation is to analyse the flow behaviour around the airfoil body and to calculate the performance coefficients at Reynolds Number 1.2×105 and angle of attack from -100 to 150. The section-lift and drag coefficient for an asymmetric airfoil are obtained by analysing the measured pressure distribution at pressure taps on the airfoil surface.
