Fluid Dynamics of a Partially Collapsible Stenosis in a Flow Model of the Coronary Circulation
Journal of Biomechanical Engineering, 1996The influence of passive vasomotion on the pressure drop-flow (ΔP-Q) characteristics of a partially compliant stenosis was studied in an in vitro model of the coronary circulation. Twelve stenosis models of different severities (50 to 90 percent area reduction) and degrees of flexible wall (0 to 1/2 of the wall circumference) were inserted into thin ...

Fluid dynamics of circulating fluidized beds
1997A circulating fluidized bed (CFB) is a special case of vertical gas/solid flows. The characteristic feature of these flows is that the gas flows in the opposite direction to gravity. Depending on the choice of particles, the gaseous medium and the adjusted superficial gas velocity, different types of gas/solid flow are obtained (Fig. 13.1). Because the

Dynamics of fluid circulation in coupled free and heterogeneous porous domains
Chemical Engineering Science, 2007Abstract Fluid flow in coupled free and porous domain, particularly when the porous medium is heterogeneous, is encountered in many hydro-environmental conditions, e.g., leakage from underground pipe, combined groundwater lake–subsurface interactions.

Computations of Fluid Dynamics of a 50 MWe Circulating Fluidized Bed Combustor
Industrial & Engineering Chemistry Research, 2009Gas-particle two-phase turbulent flows are numerically studied in a 50 MWe circulating fluidized bed combustor. The dense flow of particles is modeled by the frictional stress models adopted from solid mechanics theory. and the dilute flow in the so-called rapid granular flow regime is modeled from the kinetic theory of granulat flow.

Effects of atrial fibrillation on the arterial fluid dynamics: a modelling perspective
Meccanica (Milano. Print), 2018Atrial fibrillation (AF) is the most common form of arrhythmia with accelerated and irregular heart rate (HR), leading to both heart failure and stroke and being responsible for an increase in cardiovascular morbidity and mortality.

Circulation, respiration and fluid dynamics in the gastropod mollusc, Hemifusus tuba (Gmelin)
Journal of Experimental Marine Biology and Ecology, 1986Cardiac activity, respiratory rate, and fluid movements in and out of the shell and tissues of Hemifusus tuba (Gmelin) have been investigated. Estimates of cardiac output (Q) were in the range 0.1 to 2.22 ml·min−1 (in individuals of 7.0 to 14.2 cm shell length).

Macroscopic modelling of fluid dynamics in large-scale circulating fluidized beds
Progress in Energy and Combustion Science, 2006Macroscopic (semi-empirical) models for fluid dynamics of circulating fluidized bed (CFB) units are presented, with emphasize on applications for conditions relevant to industrial units such as fluidized-bed combustors. In order to make a structured analysis of the models, the CFB unit is divided into 6 fluid dynamical zones, which have been shown to ...

Fluid Dynamics of Differential Circulation Reactors using Different Mixers and Designs
Chemical Engineering & Technology, 2001In many cases, the chemical kinetic examination of heterogeneous gas catalytic reactions is conducted by means of differential circulation reactors with internal mixing. This reactor should be gradient-free and behave like an ideally stirred vessel. A condition is ideal mixing, which is achieved via large circulation ratios.
