Non continuum effects influence in splashing dynamics

We study numerically the impact of a liquid drop on a solid substrate using a numerical method that solves both the inviscid dynamics for the drop and the lubrication equation for the gas layer. In this framework, that does not depend on the gas pressure, we first characterize the splashing as function of the impact parameters. Then we introduce in the lubrication equation the correction due to non continuum effect in order to investigate the influence of such an effect on the splashing properties. The non-continuum correction affects the time and position of the jet leading to a change of the splashing dynamics with the gas pressure.
