This work focuses on the dynamical behavior of carbon nanotubes, including vibration, wave propagation and fluid-structure interaction. In the present research, transverse vibration of nano fluid conveying carbon nanotubes is investigated. To this end, based on the nonlocal and strain-inertia gradient continuum elasticity theories and by using rod and Euler-Bernoulli beam models, the system’s d...

A tactile display is a programmable device whose controlled surface is intended to be investigated by human touch, as a finger is dragged over it. It has a great number of potential applications in the field of virtual reality and elsewhere. In this research, a prototype tactile display incorporating magnetorheological (MR) fluid has been constructed and investigated. Surface force responses of...

The Alzheimer’s disease (AD) is the most frequent form of dementia worldwide. The major neuropathological hallmarks of the disease are loss of neurons and synapse, senile plaques (extracellular aggregates primarily composed of ß-amyloid; Aß) and neurofibrillary tangles (aggregates of hyperphosphorylated forms of the microtubule-associated tau protein) throughout cortical and limbic regions of t...

Rendering realistic moving water is one of the key techniques that immerse the viewers into interactive graphics world including computer games. Physical simulations based on computational fluid dynamics (CFD) is useful for rendering the realistic behaviour of water. However, real-time fluid rendering has been one of the challenging tasks because of high computational cost of CFD. According to ...

Realistically eroded terrain is a base of almost every outdoor visualization for simulators or computer games. In order to achieve convincing results physically based erosion algorithms are necessary. We present a new method that combines a non-expensive fluid simulation with an erosion algorithm. Both parts are running at interactive rates so the artist is able to influence the erosion process...

Argonne National Laboratory (ANL) recently discovered that a class of inexpensive and biologically benign fluids absorb radon gas with a high efficiency at room temperature, and release radon at slightly elevated temperatures (50-60 OC). This has led to the development of simple and inexpensive devices for continuous removal of radon from air. Such devices offer numerous advantages over convent...

Simulating natural phenomena like smoke, sand or fluid by physics-based algorithms is a very complex and important task in the visual effects industry. Animating fluids is time-consuming and the result is hard to control. There are only a few commercial fluid simulators on the market, which fit the high expectations of the effect artists. Our goal is to develop a physically correct fluid simula...

Advances in micro and nano fabrication technologies have enabled fabrication of smaller and more sensitive devices for applications not only in solid-state physics but also in medicine and biology. The demand for devices that can precisely transport material, specifically fluids are continuously increasing. Therefore, integration of various technologies with numerous functionalities in one sing...

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...
