Entropy production in Knudsen thermodynamics of compartmented systems
Timothy Chumley, Renato Feres, Zhenyi Zhang
We investigate entropy production and nonequilibrium transport in a class of random dynamical systems modeling a Knudsen gas confined to a compartmented container. The system consi…
Pulse-response analysis of a simple reaction-advection-diffusion equation
Jiasong Zhu, Renato Feres, Donsub Rim +1
We analyze a reaction-advection-diffusion (RAD) equation arising in pulse-response studies of transport and reaction in a narrow reactor tube. A short pulse of gas is injected near…
Nonholonomic billiards and bounded motion in cylinders
Christopher Cox, Renato Feres, Zijie Hu
A widely used mathematical model for the bouncing motion of an ideally elastic ball -- referred to in previous work by the first two authors and collaborators as a {\em no-slip bil…
Determination of output composition in reaction-advection-diffusion systems on network reactors
Renato Feres, Eric Pasewark, Gregory Yablonsky
We consider reaction-transport processes in open reactors in which systems of first order reactions involving a number of gas species and solid catalysts can occur at localized act…
Revisiting Maxwell-Smoluchowski theory: low surface roughness in straight channels
Timothy Chumley, Renato Feres, Luis Alberto Garcia German +1
The Maxwell-Smoluchowski (MS) theory of gas diffusion is revisited here in the context of gas transport in straight channels in the Knudsen regime of large mean free path. This cla…
Chaotic lensed billiards
Timothy Chumley, Maeve Covey, Christopher Cox +1
Lensed billiards are an extension of the notion of billiard dynamical systems obtained by adding a potential function of the form , where is a real valued con…
