Abstract

A three dimensional numerical method for the calculation of the droplet collection efficiency in the process of icing for an airplane with thrust is presented. The flowfield of air is computed by multiple blocks grid and SIMPLE method based on the obtained distribution, the governing equations of water phase are solved, and then the droplet collection efficiency is obtained. Both governing equations of gas and water phase are written in the form of typical transport equations, and are solved with a same finite volume method, which makes the development of numerical code easier. The droplet collection efficiency on a transport airplane cruise configuration with thrust or without thrust is computed, and the impingement characteristics of different diameter droplets are obtained, then the distribution of droplet collection efficiency on the airplane are yielded. The results show that the thrust effect of airplane on droplet collection coefficient on the wing, the vertical tail and the stabilizer is not obviously and can be ignored. However, the main effect of airplane with thrust on droplet collection coefficient occurs on the leading edge of the nacelle. The collection efficiency of airplane with thrust is higher than that without thrust on the leading edge of the nacelle, the droplet impact range of airplane with thrust is bigger than that of no thrust.
