An adaptive variational finite difference framework for efficient symmetric octree viscosity
(ACM, 2019-07)While pressure forces are often the bottleneck in (near-)inviscid fluid simulations, viscosity can impose orders of magnitude greater computational costs at lower Reynolds numbers. We propose an implicit octree finite ... -
Effect of Electroacidification on Ultrafiltration Performance and Physicochemical Properties of Soy Protein Extracts
(University of Waterloo, 2008-01-09)A novel approach for the production of soy protein isolates was investigated integrating electroacidification and membrane ultrafiltration. The effect of electroacidification on the ultrafiltration performance and ... -
An Efficient Geometric Multigrid Solver for Viscous Liquids
(ACM, 2019-07)We present an efficient geometric Multigrid solver for simulating viscous liquids based on the variational approach of Batty and Bridson [2008]. Although the governing equations for viscosity are elliptic, the strong ... -
Microfluidic Viscometer for Tear Films and Other Biofluids
(University of Waterloo, 2022-08-26)A microfluidic viscometer platform is developed and validated for measuring microliter-volume liquid samples, such as human tear films. The microfluidic viscometer combines an optically clear acrylic chip with a hydrophobic ... -
The modeling of blood rheology in small vessels
(University of Waterloo, 2005)Blood is a dense suspension of flexible red blood cells. In response to a background flow, these cells distribute themselves non-uniformly throughout the vessel. As a result, material properties that are well defined ... -
Monolith: a monolithic pressure-viscosity-contact solver for strong two-way rigid-rigid rigid-fluid coupling
(Association for Computing Machinery, 2020-11)We propose Monolith, a monolithic pressure-viscosity-contact solver for more accurately, robustly, and efficiently simulating non-trivial two-way interactions of rigid bodies with inviscid, viscous, or non-Newtonian liquids. ... -
Neural Network Viscosity Models for Multi-Component Liquid Mixtures
(University of Waterloo, 2009-08-31)An artificial neural network has been developed for the prediction of the kinematic viscosity of ternary, quaternary, and quinary systems. The systems investigated consisted of the following components: Heptane, Octane, ... -
Production and Characterization of Wheat Gluten Films
(University of Waterloo, 2012-12-17)Biodegradable, edible wheat gluten films offer a renewable alternative to plastic food packaging or can be incorporated directly in the food product. Wheat gluten is a good option because it forms a fibrous network, lending ... -
Rheology of Cellulose Nanocrystal Dispersions and Pickering Emulsions Stabilized by Cellulose Nanocrystals
(University of Waterloo, 2023-08-17)Dispersions and Emulsions are prevalent in our society and can be seen in various applications and industries. These include: (a) the food industry, for various products such as mayonnaise, salad dressings, sauces, and ice ... -
Variational Stokes with Polynomial Reduced Fluid Model
(University of Waterloo, 2021-01-21)Standard fluid simulators often apply operator splitting to independently solve for pressure and viscous stresses. This decoupling, however, induces incorrect free surface boundary conditions. Such methods are unable to ... -
Variational Stokes: A Unified Pressure-viscosity Solver for Accurate Viscous Liquids
(Association for Computing Machinery, 2017-07-20)We propose a novel unsteady Stokes solver for coupled viscous and pressure forces in grid-based liquid animation which yields greater accuracy and visual realism than previously achieved. Modern fluid simulators treat ...
