We perform experiments on the sloshing dynamics of liquids in a rectangular container submitted to an impulse. We show that when foam is placed on top of the liquid the oscillations of the free interface are significantly damped. The ability to reduce sloshing and associated splashing could find applications in numerous industrial processes involving liquid transport. When a container is set in...

In the present paper, cavitation bubble dynamics model for a single oscillating within droplet is improved based on classical Rayleigh–Plesset equation and effects of liquid surface tension viscosity are both considered. aspect experiment, collapsing dynamic process carried out by building high-speed photography experimental platform. addition, numerical solution collapse time also out. The fin...

The paper considers a new method to combat the secondary drops ejecting into gaseous medium when single drop impacts liquid surface. Possible increase in critical Weber number discrete of separates due stability loss Rayleigh jet has been shown experimentally. degree is commensurate with ratio surface tension coefficients liquids and can be estimated from proposed analytical ratio.

Objectives—To derive a method for retrospectively estimating cumulative exposure to organophosphate (OP) pesticides among a cross section of United Kingdom sheep dippers, as part of a wider epidemiological study of neurological abnormality within this group of workers. Methods—A hygiene study of dipping sessions at 20 farms using diazinon based dips was carried out by two experienced occupation...
