Abstract : An investigation of the pitching moment coefficient has been performed numerically for NACA0012 airfoil design in this paper. The evaluation of the aerodynamic parameter has been analyzed with various ranges of Reynolds number from lower to higher (104 < Re <105). An essential aerodynamic parameter, the pitching moment coefficient is associated with torque developed by the aerodynamic forces around the airfoil design. A novel method of higher order triangular element meshing around the airfoil design has been utilized for the present analysis. The higher order triangular meshing is efficiently performed around the airfoil by incorporating the parabolic arcs of a one-sided curved triangular element. The curved triangular element satisfies the sub-parametric transformation of finite elements. Three different triangular elements such as linear, quadratic, and cubic elements have been considered to mesh around the NACA0012 airfoil design by MATLAB code. The higher order element has proved its efficiency in analyzing the parameter with less computational time and effort which is essential to enhance the performance of aerodynamic structures.
