Wheel design optimization for locomotion in granular beds using resistive force theory
… the dynamics of wheeled locomotion through granular materials was explored. Resistive Force Theory is a new terradynamic model that simplifies the calculation of the forces applied to bodies moving through granular media because it utilizes linear superposition and is easily scalable to any …

Wheel design optimization for locomotion in granular beds using resistive force theory
… Force Theory, a general dimensionless form for granular locomotion has been discovered, which instructs how to scale size, mass, and driving parameters to relate dynamic behaviors of different locomotors in the same granular media. These scalings are experimentally confirmed with wheel pairs of …

A first order assessment of the moving granular panel filter
The capabilities of a specific moving granular panel bed filter are investigated, highlighting FBC flue gas cleanup. The continuous operability offers some advantages over the discontinuous operating mode of the static filter bed but the effects of moving granular medium are found to introduce …

Development of a reduced-order modeling technique for granular locomotion
… of a reduced-order modeling technique called granular Resistive Force Theory(RFT) for modeling wheeled locomotion on granular beds. A combination of various modeling techniques, namely plasticity-based continuum modeling, discrete element method (DEM) modeling, along with RFT and collaborative …

The effects of variation in wave period and flow asymmetry in sediment dynamics
… transition to turbulence over smooth beds has been reported previously in terms of a (single) critical flow amplitude Reynolds number, Recrit=U?a/?. On the basis of observations undertaken using sinusoidal flows (Li, 1954) and during the present study, this is found to be the case for …
