摘要

In this paper, the commercial CFD code FLUENT has been used as the modeling framework of the numerical simulation with the ice accretion model incorporated in the form of User Defined Functions (UDFs). A DPM Define Macro is used to attain the parameters about droplet impingement, and another grid motion UDF is employed to define the boundary nodes movement. The classical Messinger model is employed in the prediction of the accretion rate at each planel. To calculate the fraction of water that get into ice, a new approach is presented to take the runback water into account. In addition, the spring-based smoothing method is employed to calculate the domain nodes movement. Finally, the ice profiles on the NACA0012airfoil is obtained at different ambient temperature to validate the proposed method. The simulation results, including the maximal and the limit are well in good agreement with the experiment. Also, some discussions are presented about the collection efficiency and the mesh movement.
