To obtain water droplet impingement characteristics by Eulerian method

a math model was built.Also

a computational model of the heat load was established

which was based on the Messinger conservation of mass and energy.Focusing on the three-dimensional tailplane of a certain aircraft

the calculation of impingement characteristics and heat load was performed.It was found that the local water collection efficiency of tailplane raised from wing root to wing tip.The water local collection efficiency distributions of different slices provided a basis for the design of anti-icing system region.The results show that heat load is higher near the stagnation point

top airfoil and lower airfoil.It is concluded from the results that three electricity heating anti-icing regions are designed on the tailplane:the middle continuous heating region and the intermittent heating regions near the stagnation on the top airfoil and the lower airfoil.
