Wetting and soiling.

Faecal soiling and anal achalasia.

Feline house soiling: elimination and marking behaviors.

Although challenging at times, managing cats with elimination issues can be rewarding. The frustration in management of these cases is often a result of the lack of a proper diagnosis and random treatment application. A systematic approach to these cases should help to achieve treatment success. Also, new information should lead to further advancements in treatment.

Partial wetting in porous catalysts: wettability and wetting e&ciency

Qualitative changes in the local (pore level) wetting e&ciency of a porous catalyst as a function of catalyst wettability are proposed based on monitoring the 1-D motion of the solid-liquid-gas contact line. As catalyst wettability is increased, the resulting wetting e&ciency is likely to show two distinct transitions viz., (1) a sudden decrease that is inspired by coalescence of neighboring ri...

Automotive Soiling Simulation Based On Massive Particle Tracing

In the automotive industry Lattice-Boltzmann type flow solvers like PowerFlow from Exa Corporation are becoming increasingly important. In contrast to the traditional finite volume approach PowerFlow utilizes a hierachical cartesian grid for flow simulation. In this case study we show how to take advantage of these hierarchical grids in order to extend an existing Lattice-Boltzmann CFD environm...
