Application of Dynamic Mesh to Ice Accretion Simulation

摘要：

Re-meshing is necessary for the new computational domain due to ice accretion on the wall surface. In this paper, two different dynamic mesh models, Laplace method and local re-meshing method, are presented in this paper for ice accretion numerical simulation. Comparisons for the effectiveness and the accuracy of the proposed methods are demonstrated by application to icing on the surface of NACA0012 aerofoil in different conditions. Results show that the Laplace method is simple and computational cost is lower, but the mesh quality is degraded if the boundaries change greatly. While local re-meshing method guarantees mesh quality at a cost of computational time.
