Abstract This paper presents a study of viscous torsional vibration damper for crankshaft four-stroke diesel engine. The reliable operation widely used silicone-type depends on the ability silicone oil to absorb energy vibrations. non-Newtonian shear flow interlayer, characterised by reduction in shear-rate-dependent viscosity and moment drag forces, negatively affects damping characteristics. ...

Running Title: Transmural mechanics at a LV epicardial pacing site ABSTRACT (250 words) Left ventricular (LV) epicardial pacing acutely reduces wall thickening at the pacing site. Because LV epicardial pacing also reduces transverse shear deformation, which is related to myocardial sheet shear, we hypothesized that impaired end-systolic wall thickening at the pacing site is due to reduction in ...

Non-brownian suspensions present a transition from a newtonian behaviour in the zero-shear limit to a shear thickening behaviour at large shear rate, none of which is clearly understood so far. Here, we carry out numerical simulations of such an athermal dense suspension under shear, at imposed confining pressure. This set-up is conceptually identical to the recent experiments of Boyer and co-w...

We carried out pointwise local velocity measurements on 40 mM cetylpyridinium chloride-sodium salicylate (CPyCl-NaSal) wormlike micellar solution using high-frequency ultrasound velocimetry in a Couette shear cell. The studied wormlike solution exhibits Newtonian, shear-thinning and shear-thickening rheological behavior in a stress-controlled environment. Previous rheology, flow visualization a...

Suspensions of clay particles (laponite), mixed with poly(ethylene oxide) (PEO) undergo a dramatic shear thickening when subjected to vigorous shaking, which transforms them from a low viscosity fluid into a ‘shake-gel’, a solid with elasticity sufficient enough to support its own weight. The shake-gel is reversible, relaxing back to a fluid with a relaxation time that is strongly dependent on ...

Shear-thickening polishing is a non-traditional finishing method that uses the shear thickening effect by impacting non-Newtonian fluid over machining surface. As result, it forms velocity gradient increases viscosity sharply, producing flexible fixed abrasive tool to remove material. applied for outer surface of rotary workpiece in previous work. The material removal distribution on inner comp...
