Direct numerical simulation of free-surface and interfacial flow using the VOF method: cavitating bubble clouds and phase change
Direct Numerical Simulation of two-phase ow is used extensively for engineering research and fundamental fluid physics studies. This study is based on the Volume-Of-Fluid (VOF) method, originally created by Hirt and Nicols. This method has gained increased popularity, especially when geometric …

Finite Element Simulation of Interfacial Flows on Unstructured Meshes using a Second-order Accurate VOF Method
… first part a two-dimensional numerical model of interfacial flow phenomena has been developed, consisting of a finite element discretization of the time-dependent Navier-Stokes equations for immiscible, Newtonian, laminar, isothermal incompressible flows, with a volume-of-fluid (VOF) technique …

Flow Mechanisms and Transient Pressure Analysis Study For Multi-Stage Fractured Horizontal Wells In Shale Gas Reservoirs
… in the seepage model, especially in the linear flow model, is rarely given. Comprehensive consideration of adsorption, desorption and diffusion, using computer programming knowledge, such as shale gas reservoir fracturing horizontal well trilinear flow and five linear flow model, to research the …

Investigation of Multiphase Reactor Hydrodynamics Using Magnetic Resonance Imaging
… reaction vessels are considered: a co-current upflow gas-liquid-solid bed, a co-current downward trickle bed (gas, liquid, solid), and a gas-solid fluidised bed. These reactors were selected as they commonly demonstrate local hydrodynamic anisotropy which affects the global performance of …

Instabilities in newtonian films and nematic liquid crystal droplets
The instabilities of Newtonian films and nematic liquid crystal droplets within the framework of the long wave (lubrication) approximation are studied. For Newtonian films, it is found that, under destabilizing gravitational force, a contact line, modeled by a commonly used precursor film model, …

Free Surface Penetration of Inverted Right Circular Cones at Low Froude Number
In this thesis the impact of inverted cones on a liquid surface is studied. It is known that with the right combination of velocity, geometry, and surface treatment, a cavity of air can be formed behind an impacting body and extended for a considerable distance. Other investigators have shown that …

Mean-Field Free-Energy Lattice Boltzmann Method for Liquid-Vapor Interfacial Flows
… numerical development to simulate liquid-vapor flows and the applications to microchannels. First, we obtain a consistent non-local pressure equation for simulating liquid-vapor interfacial flows using mean-field free-energy theory. This new pressure equation is shown to be the general form of …
