A STUDY ON A CFD ANALYSIS OF PRESSURE DIFFERENCE ON NACA0012 AIRFOIL BY CHANGING GURNEY FLAP HEIGHT AND ANGLE OF ATTACK

Hardik S. Patel

Abstract :

 Study of a two–dimensional CFD analysis is done to investigate the effects of angle of attack and height 

of gurney flap on the aerodynamic characteristics of NACA0012 airfoil. Various techniques used for plotting and modelling an airfoil is seen. Different parameters used, and its effects, in analysis like domain shape, grid 
cells, number of nodes in meshing, various boundary conditions is surveyed. Change in Reynolds number of fluid results in different output hence variation of lift & drag co–efficient with change in Reynolds number is analysed. Proper 
selection of turbulence model is an essential criterion for accurate results which shows similarity to real condition. Inappropriate model gives worthless output hence selection of most accurate turbulence model for given problem is examined. Validation of computational results with available experimental data is also observed.
