A computational fluid dynamics (CFD) investigation was undertaken to investigate the differences in ground effect phenomena about the inverted Tyrrell and inverted NACA4412 aerofoils, and how these phenomena change with ground clearance. In understanding what these differences are, it is hoped to ...

Various ground clearances and angles of attack with a fixed speed of 30 m/s are applied to the NACA 4412 airfoil. Computational fluid dynamics (CFD) is used to calculate the aerodynamic coefficients acting on it. To study the influence of these two factors on the lift-to-drag ratio, 32 ...
As the AOA exceeds the critical angle, the lift coefficient reduces, and the drag coefficient increases significantly. Also, the momentum thickness at the trailing edge and the wake survey show high loss above critical AOA.doi:10.1007/s12046-023-02349-zRahal, Shubham...
Simulation results know that the coefficient drag airfoil NACA 4412 decreased 0.3%, coefficient lift decreased 0.5% and coefficient drag airfoil NACA 6412 also decreased 0.4%, coefficient lift decreased 0.7%. It can be concluded that the addition of fairing on airfoil is very influential in ...
This study demonstrates the hydrodynamic performance of a modified NACA 4412 hydrofoil and compares it with the base NACA 4412 hydrofoil in the presence of cavitation. A triangular slot has been introduced at the mid-section of the suction side of the hydrofoil to modify the flow characteristics ...
This research focuses on the performance of the 3D unsteady cavitating flow over NACA4412 hydrofoil at angle of attack 4 0 in the range of super cavitation to non-cavitation zone. The range of cavitation numbers considered from 0.3 to 1.1. The simulation has been carried out in commercial ...
