Abstract

The aerodynamic performance of airfoils for fluid analysis has essential applications in aerospace applications and renewable energy. The wind tunnel is a kind of mature analysis method. However, for non-professional organisations or individuals, the financial demands of building a full-size wind tunnel to carry out start-up analyses of an airfoil would be unacceptable. In addition to size constraints, the difficulty of maintenance and power consumption are also disadvantages of wind tunnel experiments. In this research, the aerodynamic performance of the airfoil is analyzed using computational fluid dynamics (CFD) to reduce the difficulty of fluid simulation. Therefore, the result of the effect from max camber, max camber position and thickness could be measured and calculated. The direction of optimization of the airfoil can be summarized by the analysis of these effects. The lift coefficient can be increased by reducing the thickness increasing the camber or moving back to the max camber position. The drag coefficient can be reduced by reducing both thickness and camber or by moving forward to the max camber position. Numerical simulation and fluid analysis can replace some wind tunnel experiments and flight tests, reducing research costs and improving research efficiency.
