Determination of Characteristic Transport Coefficients of Porous Media from Volumetric Images using the Diffuse Interface Method
(University of Waterloo, 2021-11-24)Transport in engineered materials such as electrodes, membranes, filters, and natural materials such as rock, sand, soil can be modeled as transport in porous media. Direct Numerical Simulations (DNS) on volumetric images ... -
Development of a predictive model for the VAPEX process.
(University of Waterloo, 2019-01-11)Heavy oil in-situ recovery in Canada is largely achieved through energy intensive and en- vironmentally detrimental steam assisted gravity drainage (SAGD). By exchanging steam for a vapour solvent, it has been shown ... -
Diffuse Solid-Fluid Interface Method for Dispersed Multiphase Flows
(University of Waterloo, 2018-08-30)Industrial chemical engineering processes such as bubble columns, reactors and separators involve multiphase flows of two or more fluids. In order to improve the design and operation of these processes, an understanding ... -
Formation and Field-switching Dynamics of Nematic Droplets
(University of Waterloo, 2017-08-23)Liquid crystals (LCs) refer to a class of materials which have anisotropic properties. They are used in many technological applications ranging from displays to biological sensors. One example of a category of technologically ... -
Iterative Coupled Shell/Tube Simulation of Waste Heat Boilers using Computational Multiphysics
(University of Waterloo, 2019-08-02)Removal of sulphur from fossil fuels is important in order to avoid the emission of sulphur oxides into the atmosphere, exposure to which has negative health and environ- mental effects. Sulphur is removed from refinery ... -
Multiphysics Modelling of Liquid Crystal Based Adaptive Lenses
(University of Waterloo, 2020-09-30)Conventional lenses are limited by their fixed shaped and optical properties. Liquid crystal adaptive lenses (LCLAs) are a promising candidate to move beyond these limitations thanks their tuneable optical properties. A ... -
Simulation-based Design of Bioreactors Using Computational Multiphysics
(University of Waterloo, 2021-01-28)The Covid-19 pandemic highlighted the importance of quickly scaling up the production of vaccines and other pharmaceutical products. These products are typically made within bioreactors: vessels that carry out bioreactions ... -
Simulation-based Design of In-Plane Switching Liquid Crystalline Display Pixels
(University of Waterloo, 2016-08-25)Liquid crystal displays (LCDs) constitute an important class of modern display tech- nologies. Their light-weight nature, coupled with their favourable power consumption char- acteristics make them useful in applications ... -
Simulation-based Design of Temperature-responsive Nematic Elastomers
(University of Waterloo, 2017-06-16)Liquid crystal elastomers (LCEs) are a class of polymer networks which involve the incorporation of liquid crystal (LC) molecules into their polymer backbone or side chain. This results in anisotropy in their mechanical, ... -
A Topology-Based Method for the Compartmentalization of Multiphysics Flows
(University of Waterloo, 2020-09-28)Continuum simulations of multiphysics processes are costly due to the coupling of transport phenomena. Compartment modelling decouples hydrodynamics from other transport phenomena, offering a low-cost simulation alternative ...
