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 ...
The flow characteristics over NACA4412 airfoil near stall are investigated using large eddy simulation (LES) at the Reynolds number of 1.64×106 based on the chord length (c) and free stream velocity (U∞). This flow is challenging to simulate because it contains thin turbulent boundary layer,...

In the present work, experimentation of NACA 4412 aerofoil is done to calculate the performance coefficients at Re = 92,500 (based on chord length) for the angle of attack varying from 0掳 to 18掳. Fabrication of the aerofoil is done using a 3D printer. Polylactic acid (PLA) material is...
We carried out high-fidelity large-eddy simulations to investigate the effects of uniform blowing and uniform suction on the aerodynamic efficiency of a NACA4412 airfoil at the moderate Reynolds number based on chord length and incoming velocity of Rec=200,000. We found that uniform blowing ...
This theory was applied to turbine blade to optimize various design factors like angle of attack ( 伪 ), wind flow angle ( ) and blade pitch angle ( 尾 ), chord length of every sectional part of blade (c) and number of blades (N) and also to increase the smooth functioning of wind...
This paper focuses on the delay of boundary layer separation of 2D NACA 4412 by suction using CFD analysis. Picking out the right suction position augments the aerodynamic performance. So a slot with a width of 2% of the chord length is placed at five different locations starting from 48% ...
