Physics-Based Simulations for Fluid Mixtures Dongwoon Lee Doctor of Philosophy Graduate Department of Computer Science University of Toronto 2007 We develop a physics-based particle method to simulate various fluid mixture effects. A particle method is chosen over a grid-based method because we believe a particle method is more intuitive and better suited for handling physical and chemical inte...

the pomegranate juice with high nutritional value has turbid appearance that makes it difficult to preserve and concentrate. microfiltration is useful process which can clarify it. one of the most important problems in this process is fouling phenomenon which affected by several parameters. the effects of fluid velocity, transmembrane pressure, membrane type and its pore size on membrane foulin...

Wetting and drying of a rigid substrate by a Lennard-Jones fluid in molecular dynamics simulations is reported. The size of the substrate particles, being smaller than the fluid particles in former simulations, is now taken to be equal to, respectively larger than, that of the fluid particles. Recently, for the latter type of system a first order drying transition has been reported. Like before...

In this work, the characteristics of flow and heat transfer of a fluid containing nano particles of aluminum oxide with the water volume fraction (0.1-0.2-0.3)(V/V) percent of the reports. The overall heat transfer coefficient, heat transfer and the average heat transfer fluid containing nano water - aluminum oxide in a horizontal double pipe counter flow heat exchanger under turbulent flow con...

This means that the value of does not change following a particle. We say that is “conserved” following a particle. In fluid dynamics, we consider an infinite collection of fluid particles. According to (4.2), each particle maintains its value of as it moves. If we do a survey of the values of in our fluid system, let advection occur, and conduct a “follow-up” survey, we will find that exactly ...

We study the phase behavior of bowl-shaped particles using computer simulations. These particles were found experimentally to form a metastable wormlike fluid phase in which the bowl-shaped particles have a strong tendency to stack on top of each other [M. Marechal, Nano Lett. 10, 1907 (2010)]. In this work, we show that the transition from the low-density fluid to the wormlike phase has an int...

We investigate the dynamics of rigid, spherical particles of radius R sinking in a viscous fluid. Both the inertia of the particles and the fluid are neglected. We are interested in a large number N of particles with average distance d R. We investigate in which regime (in terms of N and R/d) the particles do not significantly interact and approximately sink like single particles. We rigorously...

With the scale expands, traditional deployment algorithms are becoming increasingly complicated than before, which are no longer fit for sensor networks. In order to reduce the complexity, we propose a node deployment algorithm based on viscous fluid model. In wireless sensor networks, sensor nodes are abstracted as fluid particles. Similar to the diffusion and self-propagation behavior of flui...

In purely viscous Newtonian fluids, mechanical mixing of the fluid stream as it moves through an unstructured porous medium controls the long-time dispersion of molecular tracers. In applications ranging from environmental remediation to materials processing, however, particles are transported through porous media in polymer solutions and melts, for which the fluid properties depend on the shea...
