Abstract

Abstract

A new droplet collision and coalescence model was presented,a quick_sort method for locating collision partners was also devised and based on theoretical and experimental results,further advancement was made to the droplet collision outcome.The advantages of the two implementations of SPH method were used to limit the collision of droplets to a given number of nearest droplets and define the probability of coalescence,numerical simulations were carried out for model validation. Results show that the model presented is mesh_independent and less time consuming,it can not only maintain the system momentum conservation perfectly,but not susceptible to initial droplet size distri bution as well.
