Adaptive Mesh Refinement for Two-Phase Viscoelastic Fluid Mixture Models
Bindi M. Nagda, Aaron Barrett, Boyce E. Griffith +2
Multiphase flows are an important class of fluid flow and their study facilitates the development of diverse applications in industrial, natural, and biomedical systems. We conside…
Flagellum Pumping Efficacy in Shear-Thinning Viscoelastic Fluids
Aaron Barrett, Aaron L. Fogelson, M. Gregory Forest +3
Microorganism motility often takes place within complex, viscoelastic fluid environments, e.g., sperm in cervicovaginal mucus and bacteria in biofilms. In such complex fluids, stra…
Benchmarking the Immersed Boundary Method for Viscoelastic Flows
Cole Gruninger, Aaron Barrett, Fuhui Fang +2
We present and analyze a series of benchmark tests regarding the application of the immersed boundary (IB) method to viscoelastic flows through and around non-trivial, stationary g…
A Model of Fluid-Structure and Biochemical Interactions for Applications to Subclinical Leaflet Thrombosis
Aaron Barrett, Jordan A. Brown, Margaret Anne Smith +5
Subclinical leaflet thrombosis (SLT) is a potentially serious complication of aortic valve replacement with a bioprosthetic valve in which blood clots form on the replacement valve…
Immersed boundary simulations of cell-cell interactions in whole blood
Andrew Kassen, Aaron Barrett, Varun Shankar +1
We present a new method for the geometric reconstruction of elastic surfaces simulated by the immersed boundary method with the goal of simulating the motion and interactions of ce…
A Hybrid Semi-Lagrangian Cut Cell Method for Advection-Diffusion Problems with Robin Boundary Conditions in Moving Domains
Aaron Barrett, Aaron L. Fogelson, Boyce E. Griffith
We present a new discretization for advection-diffusion problems with Robin boundary conditions on complex time-dependent domains. The method is based on second order cut cell fini…
Pump efficacy in a fluid-structure interaction model of a chain of contracting lymphangions
Hallie Elich, Aaron Barrett, Varun Shankar +1
The transport of lymph through the lymphatic vasculature is the mechanism for returning excess interstitial fluid to the circulatory system, and it is essential for fluid homeostas…
IB2d Reloaded: a more powerful Python and MATLAB implementation of the immersed boundary method
Nicholas Battista, Christopher Strickland, Aaron Barrett +1
The immersed boundary method (IB) is an elegant way to fully couple the motion of a fluid and deformations of an immersed elastic structure. In that vein, the IB2d software allows…
