In aperture counters, particles in fluid suspension flow through a small orifice or aperture, causing a change in the electrical resistance of the aperture. This change is sensed by an external electronic circuit and translated into a voltage pulse, the signal height of which is proportional to the volume of the particle in the aperture. These signal pulses are collated into a spectrum of pulse...

Abstract Current binary nanofluid synthesis methods with heat transfer additives lack an understanding of the chemistry nanoparticle-additive-base fluid interaction, which plays a significant role in adsorption surfactant on nanoparticle surface. Consequently, this leads to formation aggregates within after couple days, affecting stability colloidal suspension. Here, lithium bromide-alumina sal...

Electrorheological (ER) fluids have electrically controllable stiffness, viscosity, and heat transfer properties. Since the 1940s researchers have attempted to model the properties of ER fluids and have proposed applications which attempt to utilize their special characteristics in the operation of hydraulic valves, soft clutches, and active suspension systems. Early attempts to make these appl...

This experimental study was focused on the study of assimilatory pigments and nucleic acid levels in young plants intended for agricultural use (Zea mays) in presence of water based magnetic fluid in culture medium. The water based magnetic fluid was constituted by coating the small magnetic nanoparticles with perchloric acid and further dispersion in water. Saturation magnetization of our magn...

The cutoff wave number for shear waves in a liquid-state strongly coupled plasma was measured experimentally. The phonon spectra of random particle motion were measured at various temperatures in a monolayer dusty plasma, where microspheres interact with a Yukawa potential. In the liquid state of this particle suspension, shear waves were detected only for wavelengths smaller than 20 to 40 Wign...

We present experimental observations of the spatial distribution large inertial particles suspended in a turbulent swirling flow at high Reynolds number. The plastic are heavier than working fluid so that their dynamics results from competition between gravitation and agitation. Two suspension regimes observed. At low rotation rate confined near bottom for any size or density. rate, loosely con...

Using frozen hydrogen particles to observe rotating and quantized flows in liquid helium Gregory P. Bewley 2006 We present a novel technique for tracing liquid helium flows, and use this technique to make observations of fluid dynamics in both the normal fluid and the superfluid phases of liquid helium. To visualize fluid motions, we create a suspension of frozen hydrogen particles with diamete...
