Abstract
The boundaries of droplet collision phenomena are defined by Weber number and Impact parameter, namely(I) coalescence after minor deformation, (II) bouncing, (III) coalescence after substantial deformation, (IV) coalescence followed by separation for near head-on collisions, and (V) coalescence followed by separation for off-centre collisions. According to earlier investigation, bouncing collision of water is not observed at 1 atm. Air.n this experiment, the surfactant, Triton X100, is dissolved in water in order to change the surface tension. Observing its collision phenomena, we can find bouncing collision and the boundaries of collision is changed. The influence of the surface tension on the boundaries of droplet collision will be discussed in this experiment.
