Toward modeling thrombosis and thromboembolism in laminar and turbulent flow regimes

International Journal for Numerical Methods in Biomedical Engineering, 2022
Abstract Thrombosis and thromboembolism are deadly risk factors in blood‐contacting biomedical devices, and in‐silico models of thrombosis are attractive tools to understand the mechanics of these processes, though the simulation of thromboembolism remains underdeveloped.

Vertical slug flow in laminar regime in the liquid and turbulent regime in the bubble wake—Comparison with fully turbulent and fully laminar regimes

Chemical Engineering Science, 2008
Abstract An experimental and simulation study on free bubbling vertical slug flow in laminar regime in the main liquid and turbulent regime in the near-wake bubble region is reported. A non-intrusive image analysis technique and a previously developed slug flow simulator (SFS) were used.

Thermohydrodynamic Lubrication in Laminar and Turbulent Regimes

Journal of Lubrication Technology, 1974
The distribution of “effective viscosity”—assumed dependent on local shear and temperature—is obtained via iteration between the “long bearing” momentum and energy equations. In this treatment the shaft is isothermal and the bearing conducts heat only in the radial direction.

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 ...
