Bacteria in shear flow
… always dynamic due to the prevalence of fluid flow: creeping flow in soil, highly sheared flow in bodily conduits, and turbulent flow in rivers, streams, lakes, and oceans, as well as anthropogenic habitats such as bioreactors, heat exchangers and water supply systems. The presence of flow not …

Shear flow instabilities in stratified magnetohydrodynamics
Shear flows are ubiquitous in nature and man-made settings and they play a fundamental role in the mixing and transition to turbulence of fluid flow. Shear flow instabilities of electrically-conducting fluids play a critical role in the dynamics of astrophysical objects, such as planets, stars, …

Shear flow instabilities in viscoelastic fluids
… study of the stability of viscoelastic shear flows. It is divided into two parts: part I studies inertialess coextrusion flows at large Weissenberg number where the instabilities are due to discontinuities in the elastic properties, and part II studies the effect of elasticity on the …

High Shear Flow Properties of Nanocellulose
… is known about the effects of high or extended shear stresses typical of those experienced during typical polymer processing. High shear rates, which proportionally result in high shear stresses, have the potential to influence the alignment, degradation, and overall usability of these materials …

Shear flow visualization at high Reynolds Numbers
… efforts were concentrated on the study of flow in the wake and near the bow of the model DDG-51 Destroyer (5514). Qualitative and quantitative flow visualization methods were adapted, designed and implemented including ship-fixed and tank fixed streak videography and Digital Particle Image …

Computer simulation of shear flow in simple fluids
Computer simulation of shear flow in fluids has become an important technique in our understanding of the non-linear behaviour of fluids subjected to an external field. An important method for studying fluids from the atomic or molecular level is Molecular Dynamics. Conventional molecular dynamics …

The Effect of Shear Flow on Solidification Microstructures
… are performed to determine the effect of fluid flow near a solidifying interface on the temperature and concentration fields existing during solidification, and the changes wrought on the microstructure by those fields. The solidification interface position and speed are controlled by two …

Droplet coalescence in the shear flow of model emulsions
During the flow of an emulsion, droplets of the dispersed phase can deform, breakup, coalesce or migrate to other regions within the flow field. Understanding these different processes, both individually and jointly, is relevant, for example, to the development of morphology in immiscible …

Crackle noise from high-speed free-shear-flow turbulence
… numerical simulations (DNS) of high-speed free-shear-flow turbulence are used to assess the underlying mechanisms and quantify near-field nonlinearity as potential sources of the radiated wave field, especially the pressure skewness. Though the DNS is restricted to a modest Reynolds-number …

Upstream Migration Under Shear Flow: Force Generation and Molecular Regulation
… persistently against the direction of blood flow -- upstream migration -- is a mechanically anomalous behavior implicated in hematopoietic stem cell trafficking and immune cell surveillance. Despite the centrality of mechanical force to this process, the forces upstream-migrating cells …

Multi-scale computational modeling of particle adhesion dynamics under shear flow
… adhesion process in biological and industrial flows since these problems require modeling a wide range of spatiotemporal scales. The thesis is focused on multiscale modeling of particle adhesion process in shear flow with broad applications to practical suspension flow problems. The …

Migration of an intruder particle in a boundary driven shear flow
… a single large spherical intruder in a Couette shear flow composed of uniform sized particles. The simulation results are useful in providing a numerical reproduction of the experiments for size segregation and mixing. This in turn has a major importance in many industries which are concerned …

Conformational and Orientational Dynamics of Semi-Rigid Macromolecules in Shear Flow
… stability of aqueous Poly-L-Lysine solutions in shear flow. Poly-L-lysine exists as an $\alpha$-helix at high pH and a random coil at neutral pH. When the $\alpha$-helix is heated above 27$\sp\circ$C, the macromolecule undergoes a conformational transition to a $\beta$-sheet. In this study, the …
