Shapes, forces, and torques of compressed elastic fluid interfaces: beyond axisymmetric configurations
Xinyi Liu, Neelesh A. Patankar, Leroy L. Jia
Inspired by the classical Plateau-Douglas problem for soap films bounded by two closed curves, we solve an analogous problem for fluid interfaces with fixed surface area and resist…
Preventing mass loss in the standard level set method: New insights from variational analyses
Kaustubh Khedkar, Amirreza Charchi Mamaghani, Pieter Ghysels +2
For decades, the computational multiphase flow community has grappled with mass loss in the level set method. Numerous solutions have been proposed, from fixing the reinitializatio…
Perspectives on physics-based one-dimensional modeling of lung physiology
Aranyak Chakravarty, Debjit Kundu, Mahesh V. Panchagnula +2
The need to understand how infection spreads to the deep lung was acutely realized during the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) pandemic. The challenge o…
Neurological disorders leading to mechanical dysfunction of the esophagus: an emergent behavior of a neuromechanical dynamical system
Guy Elisha, Sourav Halder, Xinyi Liu +4
An understanding how neurological disorders lead to mechanical dysfunction of the esophagus requires knowledge of the neural circuit of the enteric nervous system. Historically, th…
Direct and retrograde signal propagation in unidirectionally coupled Wilson-Cowan oscillators
Guy Elisha, Richard Gast, Sourav Halder +4
Certain biological systems exhibit both direct and retrograde propagating wave signals, despite unidirectional neural coupling. However, there is no model to explain this. Therefor…
A unified constraint formulation of immersed body techniques for coupled fluid-solid motion: continuous equations and numerical algorithms
Amneet Pal Singh Bhalla, Neelesh A. Patankar
Numerical simulation of moving immersed solid bodies in fluids is now practiced routinely following pioneering work of Peskin and co-workers on immersed boundary method (IBM), Glow…
