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…
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…
