AI 中文摘要
我们从能量耗散的角度建立了润湿与莱顿弗罗斯特撞击条件下液滴最大铺展之间的普适映射，后者在液滴与基底之间具有稳定的蒸气膜。实验和直接数值模拟表明，该映射在奥内佐格数和韦伯数的两到三个数量级范围内仍然有效。该框架为将已确立的润湿撞击预测转换为莱顿弗罗斯特撞击预测提供了一条简单途径，对预测和控制液滴撞击具有重要意义。
英文摘要
We establish a universal mapping between the maximum spreading of a drop under wetting and Leidenfrost impact conditions from an energy-dissipation perspective, with the latter featuring a stable vapor film between the drop and the substrate. Experiments and direct numerical simulations demonstrate that the mapping remains valid over two to three orders of magnitude in the Ohnesorge and Weber numbers. This framework provides a simple route for converting established predictions for wetting impacts into their Leidenfrost counterparts, with implications for predicting and controlling droplet impact.
