Abstract
In order to more accurately simulate the impingement characteristics of supercooled large droplets on frozen parts,based on LEWICE model,Trujillo model and two SLD impingement models,taking NACA23012 airfoil as the research object and with the secondary development function of Fluent software,conducts the numerical simulation on the motion and impingement characteristics of SLD in consideration of the influence of deformation during movement and rebound/splash during impingement.The calculated results are compared with the experimental data of NASA.The results show that when the MVD value of SLD is large,compared with LEWICE model and Trujillo model,the calculation results of local collection efficiency of airfoil surface and impingement range calculated by combining the two models are more consistent with the test data,and the error of most of the calculation results is less than 10%compared with the test data;the larger the MVD is,the closer the calculation result of the local collection efficiency value is to the test value.关键词
