Journal of Geophysical Research: Oceans, Volume 130, Issue 12, December 2025.Abstract Pumice rafts derived from submarine eruptions can remain afloat for months or even years, traveling thousands of kilometers on ocean currents. These natural phenomena disperse marine organisms and provide important evidence for submarine volcanism yet are not fully understood.

Modelling windage power loss from an enclosed spur gear [PDF]
Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2007 Within a gearbox the majority of transmission losses can be attributed to bearing losses, meshing losses, or losses due to windage/churning. In this paper the commercial computational fluid dynamics (CFD) code Fluent 6.2.16 is applied in a two-dimensional study of windage power loss (WPL) from a single spur gear rotating in air.
