Dynamical System Governing a Viscoelastic Thermosyphon Model

Abstract

Se generalizan algunos resultados sobre el comportamiento de un termosifón que encierra un fluido Newtoniano para el caso en el que el fluido considerado es un fluido visco-elástico (no Newtoniano), para alguna situación especial.

Thermoyphons, in the engineering literature, is a device composed of a closed loop containing a fluid who motion is driven by several actions such as gravity and natural convection. Their dynamics are governing for a coupled differential nonlinear systems. In several previous work we show chaos in the fluid, even with a viscoelastic fluid. We study the asymptotic behavior depending on the relevant parameters and it is obtained through an inertial manifold.
