In this chapter we apply the macroscopic balance equations that have been developed in Chap. 3 to study a few important problems. First, the pipe flow of a Newtonian fluid is considered in Sect. 5.1; then, in Sects. 5.2 and 5.3, this case is generalized to non-Newtonian fluids, stressing how the velocity profiles and the consequent pressure drops are ...

Lab on a Chip, 2012
We report a hydroelasticity-based microfluidic oscillator that converts otherwise steady laminar flow to oscillatory flow. It incorporates an elastic diaphragm to enhance nonlinearity of the flow. Negative differential flow resistance is observed.

As briefly discussed in Chapter 4, the motion of Newtonian fluids is described by the Navier-Stokes equations. Due to the non-linear nature of these equations and the general complexity of the flow geometry, analytical solutions of Navier-Stoke’s equations has been exhibiting a major problem in fluid mechanics. The continuous development in the area of

Spiral laminar flow in arteries?
The Lancet, 1991Spiral blood-flow patterns in infrainguinal blood-vessels were observed at angioscopy in 54 patients who underwent peripheral vascular reconstruction; the endoluminal surface had spiral folds in 51 of 75 arteries examined. Spiral flow patterns, congruous with inherent endoluminal anatomical features, might more accurately represent blood-flow in ...

Aircraft Design with Active Load Alleviation and Natural Laminar Flow
, 2012Maneuver load alleviation, gust load alleviation, and natural laminar flow are integrated into aircraft conceptual design. The concurrent design of the aircraft and its active load alleviation systems can yield significant gains.

1. Blood flow patterns are poorly understood despite their impact on arterial disease. There have been few measurements in vivo of the three-dimensional blood flow patterns; we present the results of such studies using a new non-invasive in-vivo method of examining biplanar arterial blood flow patterns. 2.

The dispersion of clusters of small spherical particles (20–400 m) suspended in a liquid has been studied by subjecting them to linear two-dimensional flow fields which include pure shear as one limit pure rotation as the other with simple shear as an intermediate case.

Abstract In this chapter it is shown that solutions to the Navier-Stokes equations can be derived for steady, fully developed flow of a constant-viscosity Newtonian fluid through a cylindrical duct. Such a flow is known as a Poiseuille flow. For a pipe of circular cross section, the term Hagen-Poiseuille flow is used.

Mixing in laminar flows by chaotic advection
Il Nuovo Cimento B Series 11, 1989It is pointed out that mixing of clouds of fluid particles can take place by pure advection in laminar flows. This is illustrated in a simple model of flow consisting of the superposition of steady flow and a free oscillation mode in a shallow layer of water in a rectangular basin.
