COMPARATIVE STUDY OF BLOWING AND SUCTION SLOT GEOMETRY OPTIMIZATION ON NACA 0015 AND NACA 2412 AIRFOIL

Abstract

Many investigations have been conducted to study the effect of boundary layer flow on the NACA airfoils. The studies are conducted to measure the lift and drag coefficients in accordance with different flow conditions. Additionally, the investigations focus on the leading edge blowing or suction and zero net mass flux synthetic jet impacts on vortex flow through airfoils. There are now suction and blowing techniques that have been investigated in several tests. These tests have shown that suction and blowing have the power to alter the pressure distribution over an airfoil surface and significantly alter lift and drag coefficients. The thesis entitled "Comparative Study of Blowing and Suction Slot Geometry Optimization on NACA 0015 and NACA 2412 Airfoil" aimed to analyze the effect of different blowing and suction slot geometries on the performance of NACA 0015 and NACA 2412 airfoils. The study used computational fluid dynamics (CFD) simulations to compare the lift and drag coefficients of the airfoils with different slot geometries. The results showed that optimization of the slot geometry can significantly improve the aerodynamic performance of the airfoils. The results of this study have important implications for the design of low-drag and high-lift airfoils for various applications, such as wind turbines and aircraft. The optimization of slot geometry is a cost-effective way to improve the aerodynamic performance of airfoils, and this research provides valuable insights for engineers and researchers in the field of fluid dynamics. The study also showed that the optimal slot geometry varied between the two airfoils and was dependent on the operating conditions. In conclusion, the thesis provides a comprehensive comparative study of the effect of blowing and suction slot geometry optimization on the performance of NACA 0015 and NACA 2412 airfoils. The study highlights the importance of slot geometry optimization for improving the aerodynamic performance of airfoils and provides valuable insights for engineers and researchers in the field of fluid dynamics.
