AbstractDispersion was studied by subjecting clusters of spherical particles (20–400 μm) to laminar flow fields. The clusters were: cohesionless, consisting of particles suspended in the same liquid as the bulk medium and cohesive for which a different liquid was used to make the suspension. Both qualitative and quantitative results are presented.

Riblets are little groves dug on the surface of flying or swimming solid bodies in order to reduce their drag. Why riblets work is not known but it is believed that it is a turbulent process because they trap the main eddies that develop near the solid body surfaces.

Laminar Unidirectional Flow [PDF]
, 1997 Incompressible Newtonian fluid (ϱ η) flows steadily within the annular gap of two infinitely long cylinders (Ro, RI). The outer cylinder rotates with Ω0 the inner one with Ω I . For the case that the axial component of the velocity is equal to zero, calculate a) the velocity and pressure field, b) the moments acting on both cylinders,

Laminar Flow in Tubes with Constriction
The Physics of Fluids, 1972To understand the abnormal flow conditions caused by the presence of stenoses in arteries, an analytical solution is obtained for the steady laminar flow of an incompressible Newtonian fluid in an axisymmetric conduit with irregular surface where the spread of the surface roughness is large compared with the mean radius of the conduit.

Publisher Summary This chapter presents an overview of laminar flow. If the fully established flow in a duct is laminar; then the velocity distribution over a cross-section can be obtained quite easily, because at any given time only pressure and viscous forces act on a fluid particle.

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 ...

Starting from the differential equation of mass transfer in laminar flow and the appropriate boundary condition, expressions are derived for the rate of mass transfer from (a) a flat plate in a longitudinal fluid stream, (b) a vertical flat plate by natural convection, (c) the forward stagnation point of a sphere in a fluid stream.

Laminar compressible flow in a tube
Applied Scientific Research, 1986A two-dimensional solution for the velocity and pressure distributions in steady, laminar, isothermal flow of an ideal gas in a long tube is obtained as a double perturbation expension in \(\beta\), the radius to length ratio, and \(\in\), the relative pressure drop.

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
