Kink-kink and kink-antikink interactions with long-range tails
Ivan C. Christov, Robert J. Decker, A. Demirkaya +4
In this Letter, we address the {long-range interaction} between kinks and antikinks, as well as kinks and kinks, in field theories for . The kink-antikink interacti…
A two-fluid model for numerical simulation of shear-dominated suspension flows
Federico Municchi, Pranay P. Nagrani, Ivan C. Christov
Suspension flows are ubiquitous in nature (hemodynamics, subsurface fluid mechanics, etc.) and industrial applications (hydraulic fracturing, CO storage, etc.). However, such f…
Computational Analysis of Interfacial Dynamics in Angled Hele-Shaw Cells: Instability Regimes
Daihui Lu, Federico Municchi, Ivan C. Christov
We present a theoretical and numerical study on the (in)stability of the interface between two immiscible liquids, i.e., viscous fingering, in angled Hele-Shaw cells across a range…
On the Deformation of a Hyperelastic Tube Due to Steady Viscous Flow Within
Vishal Anand, Ivan C. Christov
In this chapter, we analyze the steady-state microscale fluid--structure interaction (FSI) between a generalized Newtonian fluid and a hyperelastic tube. Physiological flows, espec…
Revisiting steady viscous flow of a generalized Newtonian fluid through a slender elastic tube using shell theory
Vishal Anand, Ivan C. Christov
A flow vessel with an elastic wall can deform significantly due to viscous fluid flow within it, even at vanishing Reynolds number (no fluid inertia). Deformation leads to an enhan…
Long-range interactions of kinks
Ivan C. Christov, Robert J. Decker, A. Demirkaya +3
We present a computational analysis of the long-range interactions of solitary waves in higher-order field theories. Our vehicle of choice is the field theory, although we ex…
