Abstract
A systematic numerical simulation is conducted to investigate the effects of span-wise ridge ice on aerodynamic performance of airplane wing including lift and drag coefficients as well as stall condition. At first, the numerical results obtained from solving compressible viscous flow equations around NACA-23012 airfoil with simulated standard ice shape are compared with the experimental and other numerical data and a very acceptable coordination has been received. Then, the simulated ice shapes examined at a range of various shapes, sizes and locations and their effects investigated on the aerodynamic performance carefully. The results show that, increasing the size, un-smoothing the shape and placing in the maximum pressure suction on the surface make the maximum side effects on the aerodynamic performance of the wing Hence; special attention must be paid in the design of ice protection mechanism considering the above mentioned behaviors.
