• During the last fifty years a number of physical theories have been proposed in an attempt to describe analytically the behavior of pulsatile flow in the mammalian arterial system. In order to make such an approach to a system of nonuniform, viscoelastic vessels containing a non-Newtonian fluid at all possible, it becomes necessary to introduce simplifying assumptions, the judicious selection...

A simple model is developed in order to calculate the flow of current in a Faraday disc when it is delivering power to an external circuit. Several counterintuitive features emerge which are not revealed by a qualitative discussion. The argument is non-relativistic, and it is conducted in the laboratory frame of reference.

Introduction The ontology of words is highly variable. Such patterns are spoken, heard, imagined and, in a sense, ‘mirrored’ in texts and programs. While moves to naturalize language usually start with words, ontologically varied entities cannot easily be grounded in either physics or biology. Turning to contemporary cognitive science, therefore, the paper denies that brains or minds store verb...

From climatology to biofluidics, the characterization of complex flows relies on computationally expensive kinematic and kinetic measurements. In addition, such big data are difficult to handle in real time, thereby hampering advancements in the area of flow control and distributed sensing. Here, we propose a novel framework for unsupervised characterization of flow patterns through nonlinear m...

This experimental and phenomenological study investigated fluctuations characteristic frequencies of pressure drop flow pattern during boiling isobutane in a horizontal mini-channel 1.0 mm diameter. The fluid was at saturation condition 27°C, heat flux ranging between 1 80 kW/m² mass from 380 to 890 kg/(m²s). Six different patterns were identified based on the analysis images captured high-spee...

The formation of droplets in an immiscible liquid the presence different surfactants was studied experimentally using a flow-focusing microchannel. A low viscosity silicone oil (4.6 mPa s) used as continuous phase and mixture 48% w/w water 52% glycerol dispersed phase. cationic (CMCDTAB = 20 mM), anionic (CMCSDS 11 non-ionic (CMCTX100 3.5 mM) surfactant were added aqueous phase, at several conc...
