Simulating Cardiac Fluid Dynamics in the Human Heart
Marshall Davey, Charles Puelz, Simone Rossi +7
Cardiac fluid dynamics fundamentally involves interactions between complex blood flows and the structural deformations of the muscular heart walls and the thin, flexible valve leaf…
A Fourier spectral immersed boundary method with exact translation invariance, improved boundary resolution, and a divergence-free velocity field
Zhe Chen, Charles S. Peskin
This paper introduces a new immersed boundary (IB) method for viscous incompressible flow, based on a Fourier spectral method for the fluid solver and on the nonuniform fast Fourie…
Modeling the Mitral Valve
Alexander D. Kaiser
This thesis is concerned with modeling and simulation of the mitral valve, one of the four valves in the human heart. The valve is composed of leaflets attached to a ring, the free…
Optimal fenestration of the Fontan circulation
Zan Ahmad, Lynn H. Jin, Daniel J. Penny +3
In this paper, we develop a pulsatile compartmental model of the Fontan circulation and use it to explore the effects of a fenestration added to this physiology. A fenestration is…
The hydrodynamics of a twisting, bending, inextensible fiber in Stokes flow
Ondrej Maxian, Brennan Sprinkle, Charles S. Peskin +1
In swimming microorganisms and the cell cytoskeleton, inextensible fibers resist bending and twisting, and interact with the surrounding fluid to cause or resist large-scale fluid…
An Analysis of the Numerical Stability of the Immersed Boundary Method
Mengjian Hua, Charles S. Peskin
We present a numerical stability analysis of the immersed boundary(IB) method for a special case which is constructed so that Fourier analysis is applicable. We examine the stabili…
