Abstract
We investigate numerically the transient forces produced by an air-in-liquid compound drop impacting onto a solid surface. We demonstrate that the presence of a bubble in the drop decreases the impact force. This decrease can be mainly explained by a reduced area over which the impact pressure is applied. We systematically vary the bubble size to understand its effect on the maximum normal force. A simple scaling model for the maximum impact force is developed to accommodate the effect of bubble size.
