Flow through Pore-Size Graded Membrane Pore Networks
Binan Gu, Lou Kondic, Linda J. Cummings
Pore-size gradients are often used in the design of membrane filters to increase filter lifetime and ensure fuller use of the initial membrane pore volume. In this work, we impose…
Network-based membrane filters: Influence of network and pore size variability on filtration performance
Binan Gu, Lou Kondic, Linda J. Cummings
We model porous membrane filters as networks of connected cylindrical pores via a random network generation protocol, and their initial pore radii via a uniform distribution of wid…
The influence of thermal effects on the breakup of thin films of nanometric thickness
Ryan H. Allaire, Linda J. Cummings, Lou Kondic
We apply a previously developed asymptotic model (J. Fluid. Mech. 915, A133 (2021)) to study instabilities of free surface films of nanometric thickness on thermally conductive sub…
Filtration with multiple species of particles
Yixuan Sun, Lou Kondic, Linda J. Cummings
Filtration of feed containing multiple species of particles is a common process in the industrial setting. In this work we propose a model for filtration of a suspension containing…
A Graphical Representation of Membrane Filtration
Binan Gu, Lou Kondic, Linda J. Cummings
We analyze the performance of membrane filters represented by pore networks using two criteria: 1) total volumetric throughput of filtrate over the filter lifetime and 2) accumulat…
Effects of spatially-varying substrate anchoring on instabilities and dewetting of thin Nematic Liquid Crystal films
M. Lam, L. Kondic, L. Cummings
Partially wetting nematic liquid crystal (NLC) films on substrates are unstable to dewetting-type instabilities due to destablizing solid/NLC interaction forces. These instabilitie…
On efficient asymptotic modelling of thin films on thermally conductive substrates
Ryan H. Allaire, Linda J. Cummings, Lou Kondic
We consider a free surface thin film placed on a thermally conductive substrate and exposed to an external heat source in a setup where the heat absorption depends on the local fil…
Modeling and design optimization for pleated membrane filters
Yixuan Sun, Pejman Sanaei, Lou Kondic +1
Pleated membrane filters, which offer larger surface area to volume ratios than unpleated membrane filters, are used in a wide variety of applications. However, the performance of…
Computing dynamics of thin films via large scale GPU-based simulations
Michael-Angelo Y. -H. Lam, Linda J. Cummings, Lou Kondic
We present the results of large scale simulations of 4th order nonlinear partial differential equations of dif- fusion type that are typically encountered when modeling dynamics of…
Stability of thin fluid films characterised by a complex form of structural/effective disjoining pressure
Michael-Angelo Y. -H. Lam, Linda J. Cummings, Lou Kondic
We discuss instabilities of fluid films of nanoscale thickness, with a particular focus on films where the destabilising mechanism allows for linear instability, metastability, and…
Interfacial deformation and jetting of a magnetic fluid
Shahriar Afkhami, Linda J. Cummings, Ian M. Griffiths
An attractive technique for forming and collecting aggregates of magnetic material at a liquid--air interface by an applied magnetic field gradient was recently addressed theoretic…
Note on the hydrodynamic description of thin nematic films: strong anchoring model
Te-Sheng Lin, Linda J. Cummings, Andrew J. Archer +2
We discuss the long-wave hydrodynamic model for a thin film of nematic liquid crystal in the limit of strong anchoring at the free surface and at the substrate. We rigorously clari…
