Thermally activated dislocation motion including inertial effects in solid solutions
… coefficient for a small viscous drag. This inertial effect determines how far a dislocation will travel after breaking away from an obstacle. The stress required to break away a dislocation does not change during the normal-superconducting transition when the damping coefficient decreases~ …

Inertial Effects on Particle Interactions in Viscous Flows (fluid-Solid, Low Reynolds Number)
… and applying Stokes flow techniques the first inertial correction to the Stokes velocity and pressure fields and the corresponding force for each particle are evaluated to O(R(epsilon)('2)), where R is the particle Reynolds number and (epsilon) is the ratio of the radius to the distance between …

Physically-based animation of plant motions
… area is the incorporation of complicated non-inertial effects into plant motion. Previous works tend to either focus on quasistatic simulations - which by defnition assume the absence of non-inertial effects - or ignore secondary motion in their dynamics calculations altogether. Either of …

Image-Based Pore-Scale Modeling of Inertial Flow in Porous Media and Propped Fractures
… and fundamentally understanding the pore-scale inertial flow is important to oil and gas production in hydraulic fractures. Image-based pore-scale modeling is a powerful approach to obtain macroscopic transport properties of porous media, which are traditionally obtained from experiments and …

Energy methods for analyzing drag and inertia in cycling kinematics
A model was developed for measuring the drag and effects of inertia for a cyclist during a race. Professional cyclist data from the Tour de France was acquired for several athletes. The data contained elevation, distance, velocity, and power as a function of time. Rolling resistance, drag, inertial …

An experimental analysis of an impedance pump as a model for segmentation in the intestine
… numbers ranging from 13-1350, the viscous and inertial effects of the fluid response created interesting pressure responses. The system was found to have a natural frequency near 1.69 Hz and exhibited frequency doubling. The dimensionless pressure and time responses showed a complicated …

Bulk Growth of Semiconductor Crystals in a Magnetic Field: A Study of Dopant Transport
… magnetic field is sufficiently strong that inertial effects and convective heat transfer are negligible. We divide the semiconductor melt into (1) mass-diffusion boundary layers where convective and diffusive mass transfer are comparable, and (2) a core region where diffusion is negligible, …

Experiments with impulsive motion of a foil to generate large lift and thrust forces
… These strokes take advantage of added mass/inertial effects to produce propulsive forces useful for maintaining position or orientation or for precise maneuverability. Various novel combinations of heave and pitch motions were tested and dye visualization was performed with a custom wing to …

Review of flapping foil actuation and testing of impulsive motions for large, transient lift and thrust profiles
… onetime strokes take advantage of added mass/inertial effects and large, stably attached vortices to avoid delay due to the realization of a jet wake for propulsion [1]. Previous work has produced trajectories, characterized by heave and pitch, for which the lift and thrust profiles were …

Micro-mechanical logic for field produceable gate arrays
… Number is undertaken. Viscous forces dominate inertial forces at low Reynolds Number flows at low pressure. Thus devices based on non-linear inertial effects at high Reynolds numbers can not be scaled down to micron-sizes. Bubble microfluidic logic gates are invented to tackle the above …
