Aeolian Creep Transport: Theory and Experiment

Laboratory Simulation of Aeolian Sand Transport and

This paper discusses the possibilities of laboratory simulation of large-scale flow around dunes, both with and without saltation, and the study of the physics of the small-scale particle motion occurring on a sand surface composed of like-moveable particles. Physics of the atmospheric boundary layer are presented in the context of laboratory applications. The governing equations of fluid and/o...

Periodic trajectories in Aeolian sand transport

Aeolian sand transport with collisional suspension

Aeolian transport is an important mechanism for the transport of sand on Earth and on Mars. Dust and sand storms are common occurrences on Mars and windblown sand is responsible for many of the observed surface features, such as dune fields. A better understanding of Aeolian transport could also lead to improvements in pneumatic conveying of materials to be mined for life support on the surface...

Connecting aeolian sediment transport with foredune development

Foredune volume is an important factor for coastal safety and depends on the balance between erosion through wave attack and sediment input via aeolian transport. Dune erosion can be simulated with good accuracy, but predictions of aeolian sediment transport into the foredunes are still difficult to make. As part of a larger project that aims to model foredune development over decades, the goal...

Rapid Spacetime Transport and Machian Mass Fluctuations: Theory and Experiment

The equations of physics, generally, are invariant under the symmetry groups of infinitesimal space and time translations. This means that energy and momentum are conserved in “isolated” systems, that is, systems that do not couple physically to anything outside of themselves. Among the propellantless propulsion schemes of interest in the context of “breakthrough propulsion physics”, however, a...
