“…This theory agrees with the experiments reported by Thoroddsen [15]. Purvis and Smith [11] and later Quero et al [12] dealt with Super Large Droplets (SLD) impacting on a thin water layer. The simulations resorted to a two-dimensional approximation and were compared to experiments performed under similar conditions.…”

“…The industrial applications are manifold including in particular ship slamming, sloshing and granular flows on chutes [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. There is also a huge number of biomedical applications [21][22][23][24][25][26][27][28][29][30][31], while sports applications are such as in skeleton bobsleigh.…”

Solid-solid and solid-fluid impacts and bouncing are the concern here. A theoretical study is presented on fluid-body interaction in which the motion of the body and the fluid influence each other nonlinearly. There could also be many bodies involved. The clashing refers to solid-solid impacts arising from fluid-body interaction in a channel, while the skimming refers to another area where a thin body impacts obliquely upon a fluid surface. Bouncing usually then follows in both areas. The main new contribution concerns the influences of thickness and camber which lead to a different and more general form of clashing and hence bouncing.

“…In many cases air or another surrounding medium is also present, yielding possible interactions of at least two fluids in the gap between the bodies. Successive impacts and re-impingements of water droplets combined with air effects in particular have crucial effects on icing of aircraft wings (Purvis & Smith 2004a, b, 2005a, as seen most recently in the experimental and computational works of Tan & Papadakis (2005) and Quero et al (2006). Our principal concern here is with air and water as the two fluids involved between the two solid bodies.…”

“…The approach of one solid body towards another solid body with liquid between them, and the subsequent squeezing and impact, has diverse applications and interest not only in droplet impact concerned with aircraft or rotorcraft icing (Gent, Dart & Cansdale 2001, Tan & Papadakis 2005, Quero et al 2006) but also in food manufacture, composites manufacture, coating problems, squeeze films, sport-related impacts and meteor cratering. In many cases air or another surrounding medium is also present, yielding possible interactions of at least two fluids in the gap between the bodies.…”

Trapping of air in impact between a body and shallow water

Near-impact behaviour is investigated for a solid body approaching another solid body with two immiscible incompressible viscous fluids occupying the gap in between. The fluids have viscosity and density ratios which are extreme, the most notable combination being water and air, such that either or both of the bodies are covered by a thin film of water. Air–water interaction and the commonly observed phenomenon of air trapping are of concern in the presence of the two or three thin layers and one or two interfaces. The subcritical regime is of most practical significance here and it leads physically to the effect of inviscid water dynamics coupling with a viscous-dominated air response locally. This physical mechanism induces touchdown (or an approach to touchdown), which is found to occur in the sense that the scaled air-gap thickness shrinks towards zero within a finite scaled time according to analysis performed hand in hand with computation. A global influence on the local touchdown properties is also identified. Comparisons with computations prove favourable. Air trapping is produced between two touchdown positions, at each of which there is a pressure peak; an oblique approach would not affect the finding unless the approach itself is extremely shallow. The mechanism of air–water interaction leading to air trapping is suggested as a quite wide-ranging result.
