Abstract: Air cushioning in droplet impacts will be investigated. A model will be presented, which couples an inviscid liquid droplet to a gas film satisfying a lubricating squeeze film equation. As the droplet approaches impact a high pressure is generated in the gas film, which causes the droplet free-surface to deform and ultimately trap a gas bubble. Predictions of the size of this trapped bubble will be made and compared to experimental data.
