The presence of nanoparticles in a millimetric liquid drop impacting on solid surface can suppress splashing at higher impact velocities. This mechanism is affected by the concentration and coating molecules their surface.

We investigate the impact of droplets of dense suspensions onto a solid substrate. We show that a global hydrodynamic balance is unable to predict the splash onset and propose to replace it by an energy balance at the level of the particles in the suspension. We experimentally verify that the resulting, particle-based Weber number gives a reliable, particle size and density dependent splash ons...

Slag splashing operations at the end of converter blow process can improve furnace liner life and operation rate. However, effect factors on slag actual dimensions is yet to be fully understood. A three-dimensional transient mathematical model coupled with response surface analysis has been established investigate effects amount remaining slag, oxygen lance height, top-blowing nitrogen flowrate...

Oblique impact of droplet onto a deep liquid pool is frequently observed in nature. As for engineering applications, the subsequent phenomenon of oblique droplet impact is of great significance for a proper design of the vanes in the extreme ultraviolet (EUV) chamber of ASML to prevent contamination. During the impact, the pool surface deforms and a cavity is generated, which later on collapses...
