It is also preferred as it increases pressure on the pressure side of the airfoil thus increasing the lift. Gurney flaps delay the onset of boundary layer separation in fluid flows. In the present research, analysis is performed on NACA4412 airfoil attached with gurney flap of different lengths...

using experimental data obtained from Cranfield’s 8′ × 6′ low speed wind tunnel, for a NACA 643–418 aerofoil. The first program was written by Eppler and Somers [298], and the second by van Ingen [299]. Both programs use integral methods to calculate...
NACA4412 airfoil trailing edge is analyzed with the models.The pressure distribution on the wall surface,velocity profile distribution and Reynolds stress distribution obtained with the three models are compared.The numerical results obtained using the three turbulence models agree with the experimental ...
Pressure distribution over the two airfoils was obtained. It was evident from the pressure distributions that the modified airfoil exhibits significant aerodynamic performance at high angles of attack. We can infer that these effects will be advantageous for maneuverability and post-stall behavior.Md. ...

The hydrodynamic performance is quantified in terms of coefficient of lift, coefficient of drag, lift to drag ratio, static pressure distribution, and cavity length at various cavitation numbers and angles of attack. From the assessment, it is observed that for 8 degrees angle of attack, the ...
