This study examined shape changes in two typical wastewater flocs subjected to cyclic freezing and thawing and the associated force exerted by the ice front. While freezing, the engulfing ice front gradually pulled the floc apart. Subsequent thawing only partially restored the floc's shape. By the Maxwell model, used to interpret gross shape deformations, both flocs were visco-elastic objects e...

In recent years pavement maintenance planning has become a main task among highway agencies. In order to determine the structural capacity of a flexible pavement, non-destructive testing equipment is used. Many countries use the falling weight deflectometer (FWD). It is possible to obtain deflection data and backcalculate the pavements’ mechanical properties. However, the method used affects th...

The present investigation studies the behavior of steady flow of visco-elastic liquid between two porous coaxial circular cylinders, where both the cylinders are rotating with different uniform angular velocities about the common axis. In addition, the inner cylinder has uniform velocity along the axis and the visco-elastic fluid, which is a Walters liquid B′, is allowed to flow in the annulus....

This paper is an pedagogical essay on the scenario of the instabilities and the transition to turbulence in visco-elastic polymer flows. When polymers are long, they get easily stretched by the shear present in flows, and the viscosity of the solution or melt is large. As a result, inertial effects are usually negligible as the Reynolds numbers are small but the fluid is strongly nonNewtonian d...

temper rolling or skin pass rolling is one of cold rolling processes composed of a horizontal pass cold rolling mill stand. in this process, the thick strip is subjected to very light reduction (0.5–4%) in thickness in the presence of high friction amplitudes. one of the basic parameters of strip rolling processes is temper rolling force. a new rolling force model has been proposed for temper r...

The torsional dynamic characteristics of an automotive clutch are simulated by ®ve lumped parameter linear or nonlinear models. Each nonlinear model includes visco-elastic and dry friction elements. Dynamic sti€ness and energy dissipation spectra clearly show excitation amplitude and frequency dependent behavior. Also, dynamic hysteresis curves are predicted and analyzed. The proposed models co...

At the cellular scale, blood fluidity and mass transport depend on the dynamics of red blood cells in blood flow, specifically on their deformation and orientation. These dynamics are governed by cellular rheological properties, such as internal viscosity and cytoskeleton elasticity. In diseases in which cell rheology is altered genetically or by parasitic invasion or by changes in the microenv...
