Peristaltic regimes in esophageal transport
Guy Elisha, Shashank Acharya, Sourav Halder +5
A FLIP device gives cross-sectional area along the length of the esophagus and one pressure measurement, both as a function of time. Deducing mechanical properties of the esophagus…
Esophageal virtual disease landscape using mechanics-informed machine learning
Sourav Halder, Jun Yamasaki, Shashank Acharya +6
The pathogenesis of esophageal disorders is related to the esophageal wall mechanics. Therefore, to understand the underlying fundamental mechanisms behind various esophageal disor…
Fluid-structure instability forecasts thoracic aortic aneurysm progression
Tom Y. Zhao, Ethan M. I. Johnson, Guy Elisha +5
The basic mechanism driving aneurysm growth is unknown. Currently, clinical diagnosis of an aneurysm is mainly informed by retrospective tracking of its size and growth rate. Howev…
A Fully Resolved Multiphysics Model of Gastric Peristalsis and Bolus Emptying in the Upper Gastrointestinal Tract
Shashank Acharya, Sourav Halder, Wenjun Kou +3
Over the past few decades, in silico modeling of organ systems has significantly furthered our understanding of their physiology and biomechanical function. In this work, we presen…
The thermodynamic principle determining the interface temperature during phase change
Tom Y. Zhao, Neelesh A. Patankar
What is the interface temperature during phase transition (for instance, from liquid to vapor)? This question remains fundamentally unresolved. In the modeling of heat transfer pro…
Handling Neumann and Robin boundary conditions in a fictitious domain volume penalization framework
Ramakrishnan Thirumalaisamy, Neelesh A. Patankar, Amneet Pal Singh Bhalla
Sakurai et al. (J Comput Phys, 2019) presented a flux-based volume penalization (VP) approach for imposing inhomogeneous Neumann boundary conditions on embedded interfaces. The flu…
