International Journal for Numerical Methods in Fluids, Volume 92, Issue 12, Page 1975-2008, December 2020., 2020 A highly accurate boundary integral method for simulating surfactant‐covered droplets in two‐dimensional Stokes flow with solid objects and walls. A spectrally accurate Ewald summation method is used for efficient computation of periodic solutions, together with a new symmetric Ewald decomposition of the 2D stresslet and truncation error estimates. The

AIP Advances, 2017 We use discrete element modelling to simulate a system of sand being released underwater, similar to the process of releasing sediment tailings back into the sea in nodule harvesting, in 2D. The force model includes concentration-dependent drag, buoyancy,

Modeling creeping flows in porous media using regularized Stokeslets
Physical Review Fluids, 2022 Flows in porous media in the low Reynolds number regime are often modeled by the Brinkman equations. Analytical solutions to these equations are limited to standard geometries. Finite volume or element schemes can be used in more complicated geometries, but become cumbersome when there are moving boundaries that require frequent remeshing of the domain.

Hybrid modeling frameworks of tumor development and treatment
WIREs Systems Biology and Medicine, Volume 12, Issue 1, January/February 2020., 2020 Hybrid modeling framework of cancer combines three classes of mathematical models: data‐driven, physics‐based, and optimization for development of a clinically relevant and quantitative decision‐making system for personalized medicine. Abstract Tumors are complex multicellular heterogeneous systems comprised of components that interact with and modify ...

Mixing and transport by ciliary carpets: a numerical study [PDF]
, 2013 We use a 3D computational model to study the fluid transport and mixing due to the beating of an infinite array of cilia. In accord with recent experiments, we observe two distinct regions: a fluid transport region above the cilia and a fluid mixing ...

Creeping motion of a solid particle inside a spherical elastic cavity [PDF]
, 2018 On the basis of the linear hydrodynamic equations, we present an analytical theory for the low-Reynolds-number motion of a solid particle moving inside a larger spherical elastic cavity which can be seen as a model system for a fluid vesicle.

A mathematical model for top-shelf vertigo: the role of sedimenting otoconia in BPPV [PDF]
, 2003 Benign Paroxysmal Positional Vertigo (BPPV) is a mechanical disorder of the vestibular system in which calcite particles called otoconia interfere with the mechanical functioning of the fluid-filled semicircular canals normally used to sense rotation ...

Regularized Stokeslet surfaces
Journal of Computational PhysicsAn extension of the Method of Regularized Stokeslets (MRS) in three dimensions is developed for triangulated surfaces with a piecewise linear force distribution. The method extends the regularized Stokeslet segment methodology used for piecewise linear curves.
