Witryna8 lut 2024 · We investigate the dynamics of drop impacts on dry solid surfaces. By synchronising high-speed photography with fast force sensing, we simultaneously measure the temporal evolution of the shape and impact force of impacting drops over a wide range of Reynolds numbers ( R e ). Witryna1 mar 2001 · The spread and rebound of droplets upon impact on flat surfaces at room temperature were studied over a wide range of impact velocities (0.5–6 m/s), …
Witryna15 cze 2024 · We demonstrate that the addition of a bubble in the drop decreases its maximum spreading. This decrease is explained by the lower kinetic energy of the drop, but also amplified by the formation of a vertical jet emerging from its center, and a relative increase in the viscous dissipation. WitrynaCompositions which contain, as the active ingredients, a combination of a heterocyclic compound of the general formula (I) and an organophosphous compound, in addition to an amorphous silica additive selected from the class consisting of: (a) an amorphous silica obtained by a process, wherein an amorphous silica hydrate, which has been …
