The target of the task is to find out the lift coefficient and drag coefficient at different leading-edge radii of NACA 2421 aerofoil and compared the results of the Elliptical, Circular, Cone leading edge of the aerofoil with standard baseline airfoil. 展开 ...
Analysis is carried out and coefficient of lift, drag, airfoil performance and pressure distribution is studied. In gurney flap, the lift force increases with decreasing ground clearance due to pressure region created under the airfoil. Phenomena of gurney flap are applicable for increase in ...
GAMBIT was used to model and mesh the NACA 4412 airfoil with a chord length of one meter. For setting the boundary conditions and analyses, FLUENT was used. Coefficients of lift and drag were noted from the graphs plotted using the FLUENT software. These values for all of the forty-four ...
However, at higher cavitation numbers, the base hydrofoil exhibits slightly better performance than the modified hydrofoil in terms of lift-to-drag ratio, despite having a lower lift coefficient. Furthermore, the modified hydrofoil demonstrates improved performance at 4°, 8°, and 16° angles of ...

For angle of attack 4 0 moving from super cavitation zone ( σ =0.3) to non-cavitation zone ( σ =1.1), the lift coefficient nonlinearly grows (from 0.2 to 0.8), and cavitation length reduces.Kumar, PrabhakarShiv Nadar Institution of EminenceSingh, Srijna...
A total of 9 numerical experiments were carried out with Ansys Fluent. When the angle of attack decreases, lift coefficient increases and drag coefficient decreases resulting in a high lift-to-drag ratio: also, the lower the ground clearance, the higher the lift-to-drag ratio. It shows the ...
