Abstract We consider a classical elastohydrodynamic model of an inextensible filament undergoing planar motion in R 3 . The hydrodynamics are described by resistive force theor...

Meshing teeth pairs of involute spur gears often form the final drive high-performance motorsport transmissions. They are subject to high normal and shear loading. Under transient conditions pertaining a meshing cycle, contact alter from onset pair engagement through maximum loading, followed by separation. Sliding motion only ceases instantaneously at pitch point. The regime lubrication remain...

Predictions are provided for mixed elastohydrodynamic conditions of meshing hyoid gear teeth pairs light truck differentials. Under transient conditions, pertaining to vehicle cruising or in urban driving, the lubricant is subjected non-Newtonian traction. The complex kinematics, comprising rolling, sliding and squeeze film motions. Furthermore, instantaneously varying angled flow into contact ...

We study the behavior of single linear polyelectrolytes condensed by trivalent salt under the action of electric fields through computer simulations. The chain is unfolded when the strength of the electric field is stronger than a critical value. This critical electric field follows a scaling law against chain length, and the exponent of the scaling law is -0.77(1), smaller than the theoretical...

We consider deflections of a thin rectangular elastic plate that is submerged within a Newtonian fluid. The plate is clamped along one edge and supported horizontally over a plane horizontal wall. We consider both external driving, where the clamped edge is vibrated vertically at high frequencies, and thermal driving, where the plate fluctuates under Brownian motion. In both cases, the amplitud...

We consider the motion of a fluid-immersed negatively buoyant particle in the vicinity of a thin compressible elastic wall, a situation that arises in a variety of technological and natural settings. We use scaling arguments to establish different regimes of sliding, and complement these estimates using thin-film lubrication dynamics to determine an asymptotic theory for the sedimentation, slid...

The shape of a microchannel during flow through it is instrumental to understanding the physics that govern various phenomena ranging from rheological measurements fluids separation particles and cells. Two commonly used approaches for obtaining desired channel (for given application) are (i) fabricating in requisite (ii) actuating walls obtain shape. However, these not always viable. We propos...
