FORCED CONVECTIVE EVERSION: THE LAMINAR REGIME

Numerical Heat Transfer, Part A: Applications, 1991
The paper is a numerical exploration of the effect of convective eversion (turning the flow inside out) inside a tube with a wall temperature different from that of the fluid entering it. Three models of eversion are suggested to cover the likely behavior of practical devices under laminar conditions.

Gas/liquid dispersions with a SMX static mixer in the laminar regime

Chemical Engineering Science, 2006
A Sulzer SMX mixer was used to disperse gas into viscous, Newtonian and non-Newtonian fluids. The investigation covered the effect of the dispersed phase volume fraction, the viscosity of the continuous phase, the mixer length and the power draw. The flow regime was kept laminar in all the experiments.

Partial Journal Bearing Performance in the Laminar Regime

Journal of Lubrication Technology, 1975
In this approximate analysis of laminar journal bearing operations both the momentum and the energy equations are two dimensional, the shaft operates at a constant temperature and the bearing conducts heat in the radial direction only. Via the last of these assumptions, the equation of heat conduction is eliminated from consideration.

A Contraction-expansion Helical Mixer in the Laminar Regime

Chinese Journal of Chemical Engineering, 2014
Abstract A contraction-expansion helical mixer which combines several features, viz . helical pipes for induction of secondary flows and sudden expansion and contraction array for expansion vortices, has been designed to enhance flow mixing. A fast competitive-consecutive diazo coupling reaction is used to test the mixing efficiency of contraction ...

Full Journal Bearings in Turbulent and Laminar Regimes

Journal of Mechanical Engineering Science, 1967
An equation in lubricant pressure is derived, based on Prandtl's mixing-length theory, under general loading conditions. This non-homogeneous partial differential equation is amenable to reduction by separation of variables. One of the resulting ordinary equations is integrated directly, while the other is solved by a direct method.

Laminar regime transition for blood flow in tubes1

Biorheology, 1967
Using the Metzner and Reed method of analyzing non-Newtonian fluid flow behavior, which is based on the Rabinowitsch-Mooney equation, friction factor-Reynolds number plots were made for whole blood flowing in rigid tubes. It was found for laminar flow that blood behaved in a similar manner to other non-biologic, non-Newtonian fluids if the Reynolds ...

Performance of finite journal bearings in non-laminar lubrication regime

Tribology International, 1983
Abstract Fluid dynamic lubrication of journal bearings in a superlaminar regime, ie a transition or turbulent regime, is the subject-matter of this study. Results obtained by solving an appropriately modified Reynolds bidimensional equation have been put in the form of operating diagrams which allow the correct design of journal bearings in real ...

Co‐current stratified flow of immiscible liquids: Velocity distribution and pressure gradient in the laminar‐laminar and laminar‐turbulent regimes

The Canadian Journal of Chemical Engineering, 1981
AbstractFurther studies on the co‐current stratified flow of two immiscible liquids in closed conduits with emphasis on the laminar‐laminar and laminar‐turbulent regimes are reported. Experimental velocity distributions obtained using a photo‐chromic dye technique and pressure gradients for the flow of oil/water and oil/ethanol‐water systems in a ...

Periodic Laminar Regime

1997
Abstract The steady, elongated and closed near-wake becomes unstable whenRe> Reosc, where the subscriptosc stands for oscillation. The transverse oscillation starts at the end of the near-wake and initiates a wave along the trail as shown in Fig. 1.6(a).
