Abstract
Ice accretions on three-element airfoils and MS-317 swept wing were predicted by using CFD method. Based on Eulerian two phase flow theory, the governing equations for air and droplets were solved by using partition algorithm to obtain the water collection efficiency. The amount of ice accreted was calculated by solving the 3-D ice accretions model, and the predicted ice shape was compared with those of experimental and ice accretions software LEWICE3D results. The results show that the precision of the approach and algorithm is good. Although there are some discrepancies between the predicted ice shape and experimental ice shape, the error is less than 13. 1% in terms of the maximum thickness, and the predicted ice shape is basically the same with the experiment data in terms of type and volume.
