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.
