The Role of Elasticity on Chaotic Dynamics: Insights from Mechanics, Immunology, Ecology, and Rheology

open access: yesMathematics, 2023
Elasticity is commonly associated with regular oscillations, which are prevalent in various systems at different scales. However, chaotic oscillations are rarely connected to elasticity.

Fast Solutions for Large Reynold’s Number in a Closed-Loop Thermosyphon with Binary Fluid

open access: yesMathematics, 2022
In this work, we analyze the asymptotic behavior of the solutions for a thermosyphon model where a binary fluid is considered, a fluid containing a soluble substance, and the Reynold’s number is large.

Una introducción a la dinámica no lineal en enseñanza Secundaria [PDF]

open access: yes, 2000
An interesting study on an approach to Physics teaching of an introduction to non-linear dynamics, at a basic level, is presented here. This study, framed on the constructivist theory of learning has led to the actual possibility of explaining in ...

Asymptotic Behavior of a Viscoelastic Fluid in a Closed Loop Thermosyphon: Physical Derivation, Asymptotic Analysis, and Numerical Experiments

open access: yesAbstract and Applied Analysis, 2013
Fluids subject to thermal gradients produce complex behaviors that arise from the competition with gravitational effects. Although such sort of systems have been widely studied in the literature for simple (Newtonian) fluids, the behavior of viscoelastic
