The liquid flow inside, and the induced air flow around, a falling droplet in stagnant air was numerically investigated using the Volume of Fluid (VoF) method to describe the droplet interface. The droplet consisted of oil with the same surface tension and with viscosity as parameter. It was injected into stagnant air with an initial velocity of 1m/s; therefore the initial Weber (W e = 0.14), Reynolds (Re = 141) and Bond (Bo=2.4) *
