Abstract

Abstract: In the icing of Supercooled Large Droplet (SLD), many factors affect droplets deformation and breakup. The laws of multiple factors influencing on the deformation and breakup of droplets have not been understood clearly. Adopting numerical calculation, the effects of droplets diameter, flow field velocity and the variation of object size on SLD deformation and breakup are studied. Then a method of dividing typical flow fields region including SLD is proposed. The influence laws of different factors on the area of droplets breakup region, the efficiency of droplets collection and the distribution of sub-droplets are obtained. It's found that the SLD diameter, air velocity and leading edge radius of airfoil are positively associated with the effect of deformation and breakup to droplets impingement and collection coefficient. On this basis, a comprehensive influence parameter, X, is proposed. The results of the linear regression analysis show that X is an appropriate parameter to characterize the effects of deformation and breakup. The above work can provide reference to the calculation and test of SLD icing and the anti/de-icing design.
