A QUASI-MOLECULAR APPROACH FOR DISCRETE STUDY OF DROPLET COLLISION

A discrete numerical method based on a molecular approach has been use d as an alternative technique for the study of liquid drop dynamics, T he Weber number and the Impact number are found to be the key paramete rs that determine the outcome of collision of two liquid droplets, Thi s study confirms the experimental fact that the number of daughter dro plets resulting from the collision of two droplets increases with the Impact number for a large Weber number. The shapes of the droplets at different phases during collision are in accord with the experimental observation.
