This research paper presents the design and analysis of a NACA 0012 airfoil with a circular dent of 30 mm depth on its upper surface. The objective of this study is to investigate the effect of the dent on the airfoil's aerodynamic performance. The airfoil's geometry was modeled using a ...
The transitional flow past a NACA0012 airfoil at Reynolds numbers, Re, between 50,000 and 140,000 is investigated using experiments and low and high-fidelity numerical simulations. Variations in Reynolds number provide the quasi-steady response of the flow and resulting lift to dynamic inflow (var...
The NACA 0012 airfoil is widely used. The simple geometry and the large amount of wind tunnel data provide an excellent 2D validation case. For this case I use the Spalart-Allmaras turbulence model. Mesh The mesh is a 30,000 cell structured C-grid. The chord length is 1 m. The width ...

Separation control on NACA 0012 airfoil using momentum and wall-normal vorticity injection We numerically investigate the inuence of momentum and wall-normal vorticity injection in separation control of flow over a spanwise periodic NACA 0012 airfoil at a Reynolds number of 23,000. Large-eddy simulat...
In this case the flow over a NACA 0012 airfoil at an angle of attach of 1.49° will be simulated and the lift and drag values will be compared to published results. These results were taken with a Reynolds number of 9x106 and a chord length of 1m.* The airfoil is travelling at Mach...
