Modeling of Coronary Capillary Flow
1993The coronary capillary flow is analyzed theoretically based on the laws of continuum mechanics. The capillary is considered as a long, elastic and permeable vessel loaded externally by tissue pressure. It is subjected to periodic length changes, together with adjacent myocytes.

Capillary scale NMR flow mapping
Journal of Magnetic Resonance, 2008Stopped-flow NMR at capillary scale has many advantages over traditional methods of introducing the sample into the probe, particularly when large numbers of samples must be examined. This work describes application of a simple method for direct visualization of a sample inside the flow cell of flow NMR systems to capillary scale analysis.

The capillary flow of fluid and plastic materials that do not obey Poiseuille's Law has been subjected of recent years to very intensive study, and many hypotheses advanced which attempt to characterize the resistance to deformation of such materials.

Capillary flow in microchannels
Microfluidics and Nanofluidics, 2009The surface of microchannels, especially polymer channels, often needs to be treated to acquire specific properties. This study investigated the capillary flow and the interface behavior in several glass capillaries and fabricated microchannels using a photographic technique and image analysis.

THE temperature profile in an essentially Newtonian liquid in laminar flow in a capillary has been measured experimentally. Previously the phenomenon of capillary heating (that is, heat produced by the internal friction of liquids in flow in a capillary) had been the subject of extensive theoretical treatment1,2; but with little experimental ...

Capillary-scale polarimetry for flowing streams
The Analyst, 2001A micro-polarimeter with a 40 nL probe volume was configured so that it is compatible with capillary-scale flowing stream analysis. The optical configuration consists of two polarizing optics, a capillary, a laser source and a photodetector which is very simple to configure with low cost components. This unique polarimeter is based upon the interaction

Journal of Rheology, 1932
A further development is given in this paper of the theory of the flow of liquids in capillaries under inlet pressures that are high enough to cause an appreciable change in viscosity, such that the viscosity can no longer be treated as uniform. The results are put in the form of Poiseuille's law, with a correction factor.

β-Lactoglobulin Fibers under Capillary Flow
Biomacromolecules, 2006We describe the capillary flow behavior of gels of beta-lactoglobulin (beta-lg) containing droplets of fibrils and the shear flow alignment of beta-lg fibers in dilute aqueous solutions. Polarized optical microscopy and laser scanning confocal microscopy are used to show that capillary shear flow does not affect the fibril droplet sizes in the beta-lg ...

Capillary Flow: History, experiments and theory
Biorheology, 1981The history of capillary flow is presented from the earliest observations to the most recent experiments. Parallel theoretical developments are traced from early work on continuous fluids to modern work in which the discrete nature of each blood cell is taken into account.

Capillary Flow-Driven Heat Transfer Enhancement
Journal of Thermophysics and Heat Transfer, 2011DOI: 10.2514/1.T3747 Capillary flow in a microgroove for heat transfer enhancement is investigated. Competing effects of capillarity, wall shear,andavailable area forthe liquid flow determine the critical (maximum) heat transport capacity.A model for fluid flowandheattransferinthemicrogrooveofaV-shapedcrosssectionisdeveloped,andananalyticalsolution of ...
