Flow Maldistribution in Microsystems: Description and Effects

Volume 10: Micro- and Nano-Systems Engineering and Packaging, 2013
Flow maldistribution is a fluid-management problem of interest in engineering. It consists in the non-uniform distribution of various flows in industrial applications like multiple accesses, manifolds, bifurcations, spreaders, etc., where the fluid currents separate, detach and reattach, break from the main body of the stream and splash within the ...

Mitigation of air flow maldistribution in evaporators

Applied Thermal Engineering, 2014
Abstract Flow maldistribution in evaporators can lead to significant performance and capacity degradation. A significant amount of work has previously been published to overcome this issue. For a fixed air side maldistribution, various methods have been proposed to significantly reduce the effect on performance.

Maldistribution of heterogeneous coronary blood flow during canine endotoxin shock

Cardiovascular Research, 1991
STUDY OBJECTIVE - The aim was to investigate whether heterogeneous coronary blood flow is maldistributed during endotoxin shock. DESIGN - Variables were studied before (t = 0) and at t = 90 and t = 120 min after bolus injection of saline (n = 6) or endotoxin (n = 6). SUBJECTS - 12 anaesthetised mongrel dogs, weight 20-27 kg, were used. MEASUREMENTS AND

Flow maldistributions and hot spots in down-flow packed bed reactors

Chemical Engineering Science, 1994
A two-dimensional two-phase (heterogeneous) model that predicts flow maldistributions and hot spots in an adiabatic down-flow packed bed reactor is developed and analyzed. The model considers the effects of fluid flow, changes of physical properties, heat and mass transfer by conduction and convection, interphase gradients and reactant consumption by ...

Flow Rate Maldistribution in Multi Heated Parallel Pipes

2010 14th International Heat Transfer Conference, Volume 1, 2010
Fluids flowing in parallel pipes, undergoing evaporation, take place in heat exchangers, boilers, power plants, cooling systems and in the nuclear industry. Evaporating two-phase flow in parallel micro-channels is considered for heat removal in microelectronic devices.

Flow Maldistribution in Multichanneled Microdevices With In-Line Manifolds

Volume 9: Heat Transfer, Fluid Flows, and Thermal Systems, Parts A, B and C, 2009
This paper deals with the analyses of fluid flow distribution in a microfluidic device with in-line manifolds. The analysis was performed using commercially available microfluidic simulation software called CoventorWare™. The number of channels in the microfluidic device considered for this study was kept at ten due to limitations on the number of ...

Prediction of flow maldistribution in printed circuit heat exchanger

International Journal of Heat and Mass Transfer, 2020
Abstract The printed circuit heat exchanger (PCHE) is widely used in a variety of extremely high temperature and high pressure applications. Since the PCHE is a typical multi-channel heat exchanger, the flow maldistribution may happen in the PCHE channels. In this paper, a new mathematical model is established to predict the flow maldistribution in a

Maldistribution of the cerebral blood flow in retrograde cerebral perfusion

European Journal of Cardio-Thoracic Surgery, 1995
Retrograde cerebral perfusion (RCP) through a superior vena caval (SVC) cannula has now become a useful alternative for brain protection during aortic arch operations. However, little is still known about its physiological effects, especially regarding the flow distribution in the brain. We studied the cerebral blood flow distribution under hypothermic

Gas flow maldistribution in moving beds of monosized particles

Chemical Engineering Science, 2000
Abstract This work is concerned with the structure of moving beds, in particular the steady-state dense phase downwards flow of monosized particles in a vertical cylindrical vessel. The structure of a moving bed is probed using gas flows through a `frozen’ bed, which is a moving bed which has been carefully stopped to preserve its structure.
