Abstract: Fluid mechanics and computational analysis are useful for examining the stability and properties of the various types of airfoils used in turbine blades. With the use of computational simulation aid, the fluid dynamic properties and effectiveness of the airfoils with different shapes of mean camber line and the maximum camber were examined. This study was to find the effective turbine blade shape. Different shapes of airfoils were created by using NACA 4-digit Airfoil Generator, and computational simulations were performed. For each different type of airfoils, lift(Cl) vs. drag(Cd), lift vs. angle of attack(alpha), lift/drag vs. angle of attack, and drag vs. angle of attack are found and analyzed to find if there is a correlation between them. The presented results show that all the correlations between the dependent variables and independent variables change a lot as the Reynold number(Re) changes.vThe Cd vs. Alpha was found for varying Reynold numbers.
