This paper presents a method of dynamic compensation of creeping and drifting error of load cell response using Adaptive technique. The case is illustrated by showing how the response of a load cell can be improved. The load cell is a sensor, whose output gives an damped oscillatory response due to creeping and drifting error, in which the measured values contribute to the response parameter. S...

We investigate nonlinear phenomena in dispersed two-phase systems under creeping-flow conditions. We consider nonlinear evolution of a single deformed drop and collective dynamics of arrays of hydrodynamically coupled particles. To explore physical mechanisms of system instabilities, chaotic drop evolution, and structural transitions in particle arrays we use simple models, such as small-deform...

The effects of confinement on the dynamics of binary encounters between spherical particles in shear flow are studied for a system bounded by a single planar wall or two parallel planar walls under creeping flow conditions. We show that wall proximity gives rise to a new class of binary trajectories resulting in cross-streamline migration of the particles. In contrast, in unbounded space spheri...

A diffuse interface method is used to simulate two-phase flows with moving contact lines in 3D. The specific numerical issue is the validation of the method regarding the dynamics of moving contact lines in 3D. In particular, we aim to use the method to extend previous (2D and/or creeping-flow) work on sheardriven motion of a droplet on a wall to the full 3D problem, accounting for inertial eff...

The geotropic conduct of young rats has been discussed in a previous paper (Crozier and Pincus, 1926-27) with special reference to the angle of orientation upon an inclined plane. It was found that the angle of orientation (0) is directly proportional to the logarithm of the gravitational component (g sin ~) in the creeping plane. This is explicable as the result of the distribution of the pull...

The effect of pore-scale heterogeneity on non-Darcy flow behaviour is investigated by means of direct flow simulations on 3-D images of a beadpack, Bentheimer sandstone and Estaillades carbonate. The critical Reynolds number indicating the cessation of the creeping Darcy flow regime in Estaillades carbonate is two orders of magnitude smaller than in Bentheimer sandstone, and is three orders of ...

This study investigates the numerical solution of viscous sharp contraction flow using a time-step Taylor-Galerkin-pressure correction finite element method (T-G/P-C). Such complex problfem displays start-up, 4:1contraction creeping flow, shear viscosity and extensional responses. Here, inelastic shear-extensional model is proposed with single power-index response identical in extension, namely...

While there is abundant geomorphologic evidence for landslides in Iceland, it is in most cases unknown whether or not these landslides are actively creeping. Here we use Interferometric Synthetic Aperture Radar (InSAR) to assess its monitoring capabilities on three landslides that are known to be creeping and to survey large areas in East and Central-North Iceland in search for other creeping l...
