Bifurcations in valveless pumping techniques from a coupled fluid-structure-electrophysiology model in heart development
(2017-12-06)We explore an embryonic heart model that couples electrophysiology and muscle-force generation to flow induced using a 2𝘋 fluid-structure interaction framework based on the immersed boundary method. The propagation of ... -
Diving into a simple anguilliform swimmer’s sensitivity
(Oxford University Press, 2020-09-16)Computational models of aquatic locomotion range from modest individual simple swimmers in 2D to sophisticated 3D multi-swimmer models that attempt to parse collective behavioral dynamics. Each of these models contain a ... -
Fluid-structure interaction for the classroom: interpolation, hearts, and swimming!
(Society for Industrial and Applied Mathematics, 2021)While students may find spline interpolation quite digestible, based on their familiarity with continuity of a function and its derivatives, some of its inherent value may be missed when students only see it applied to ... -
A fully coupled fluid-structure-muscle-electrophysiology model in heart development
(Biomath Forum, 2017-03-02)The vertebrate heart begins to pump when its morphology is nothing more than a valveless tube, composed of an outer layer of myocardial cells surrounding an inner layer of endocardial cells. It has been proposed that the ... -
Hopscotching jellyfish: combining different duty cycle kinematics can lead to enhanced swimming performance
(IOP Publishing, 2021-10-26)Jellyfish (Medusozoa) have been deemed the most energy-efficient animals in the world. Their bell morphology and relatively simple nervous systems make them attractive to robotocists. Although, the science community has ... -
IB2d Reloaded: a more powerful Python and MATLAB implementation of the immersed boundary method
(Wiley, 2018-12)The immersed boundary (IB) method 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 for expedited explorations of fluid-structure ... -
Passive concentration dynamics incorporated into the library IB2d, a two-dimensional implementation of the immersed boundary method
(IOP Publishing, 2022-03-10)In this paper, we present an open-source software library that can be used to numerically simulate the advection and diffusion of a chemical concentration or heat density in a viscous fluid where a moving, elastic boundary ... -
Pulsing corals: a story of scale and mixing
(Biomath Forum, 2017-12-27)Effective methods of fluid transport vary across scale. A commonly used dimensionless number for quantifying the effective scale of fluid transport is the frequency based Reynolds number, Ref, which gives the ratio of ... -
A semi-automated finite difference mesh creation method for use with immersed boundary software IB2d and IBAMR
(IOP Publishing, 2020-11-27)Numerous fluid-structure interaction problems in biology have been investigated using the immersed boundary method. The advantage of this method is that complex geometries, e.g., internal or external morphology, can easily ... -
A swing of beauty: pendulums, fluids, forces, and computers
(MDPI, 2020-04-12)While pendulums have been around for millennia and have even managed to swing their way into undergraduate curricula, they still offer a breadth of complex dynamics to which some has still yet to have been untapped. To ...
