Impacting the Learning Experience

The availability of technology has seen the development of online asynchronous discussion boards for use in teaching and learning. This paper explores the use of this medium within a second year undergraduate business course at the University of South Australia to supplement traditional delivery methods as well as showing how this medium can be used to enhance the development of communication, ...

Drops impacting a sieve.

We study experimentally the impact of liquid drops against thin plates pierced with small holes. When the drop is larger than the hole, different situations can occur: (i) at a small velocity, the drop is entirely captured by the plate; (ii) above a threshold speed, some liquid is ejected below the surface. We characterize this critical speed and these two different situations, focusing on the ...

Viscoelasticity breaks the symmetry of impacting jets.

A jet of a Newtonian liquid impacting on a wall at right angle spreads as a thin liquid sheet which preserves the radial symmetry of the jet. We report that for a viscoelastic jet (solution of polyethylene glycol in water) this symmetry can break; close to the wall, the jet cross section becomes faceted and radial steady liquid films (wings) form, which connect the cross-section vertices to the...
