چکیده

We explore the evolution of a splash when a liquid drop impacts a smooth dry surface. There are two splashing regimes that occur when the liquid viscosity is varied as is evidenced by its dependence on ambient gas pressure. A high-viscosity drop splashes by emitting a thin sheet of liquid from a spreading liquid lamella long after the drop has first contacted the solid. Likewise, we find that there is also a delay in the ejection of a thin sheet when a low-viscosity drop splashes. We show how the ejection time of the thin sheet depends on liquid viscosity and ambient gas pressure.

An Improvement to the Properties of GAP Binder with Energetic Ionic Liquids

Glycidyl azide polymer (GAP) is used as a binder in the propellants. Energetic ionic liquids are used as a plasticizer to correct the properties of polymer. In this study, first ionic liquid was bonded to the GAP by certain amount and then the energetic anions of nitrate (NO3) and azide (N3) were used to exchange anion. FTIR analyses confirm accurately anions exchange. DSC, viscometer and heat ...

Droplet Lamella Lift Dynamics and Surface Wettability

Droplet impact on dry, smooth surfaces remains an issue for a variety of important applications such as fuel injection, spray cooling, metallurgy, pesticides and coatings. The mechanisms that initiate splashing are highly complex and differ from those on rough or pre-wetted surfaces. In this work, droplet wettability on a smooth, dry surface is examined to quantitatively evaluate its influence ...

From splashing to bouncing: The influence of viscosity on the impact of suspension droplets on a solid surface.

We experimentally investigated the splashing of dense suspension droplets impacting a solid surface, extending prior work to the regime where the viscosity of the suspending liquid becomes a significant parameter. The overall behavior can be described by a combination of two trends. The first one is that the splashing becomes favored when the kinetic energy of individual particles at the surfac...

Computer Simulation of Slag Splashing in a Steelmaking Converter

Some variables that influence the slag splashing phenomenon in an oxygen steelmaking converter are numerically analyzed in this work. The effect of lance height, jet velocity, jet exit angle and slag viscosity on the washing and ejection mechanisms of slag splashing is studied in this work employing twodimensional transient computational fluid dynamics simulations. A parameter here called avera...
