Structural electroneutrality in Onsager-Stefan-Maxwell transport with charged species

Alexander Van-Brunt, Patrick E. Farrell, Charles W. Monroe

We present a method to embed local electroneutrality within Onsager-Stefan-Maxwell electrolytic-transport models, circumventing their formulation as differential systems with an al…

Finite element methods for multicomponent convection-diffusion

Francis R. A. Aznaran, Patrick E. Farrell, Charles W. Monroe +1

We develop finite element methods for coupling the steady-state Onsager--Stefan--Maxwell equations to compressible Stokes flow. These equations describe multicomponent flow at low…

Augmented saddle point formulation of the steady-state Stefan--Maxwell diffusion problem

Alexander Van-Brunt, Patrick E. Farrell, Charles W. Monroe

We investigate structure-preserving finite element discretizations of the steady-state Stefan--Maxwell diffusion problem which governs diffusion within a phase consisting of multip…

An Adaptive Observer Design for Charge-State and Crossover Estimation in Disproportionation Redox Flow Batteries undergoing Self-Discharge

Pedro Ascencio, Kirk Smith, Charles W. Monroe +1

This article considers a model formulation and an adaptive observer design for the simultaneous estimation of the state of charge and crossover flux in disproportionation redox flo…

Faster Lead-Acid Battery Simulations from Porous-Electrode Theory: II. Asymptotic Analysis

Valentin Sulzer, S. Jon Chapman, Colin P. Please +2

Electrochemical and equivalent-circuit modelling are the two most popular approaches to battery simulation, but the former is computationally expensive and the latter provides limi…

Faster Lead-Acid Battery Simulations from Porous-Electrode Theory: I. Physical Model

Valentin Sulzer, S. Jon Chapman, Colin P. Please +2

An isothermal porous-electrode model of a discharging lead-acid battery is presented, which includes an extension of concentrated-solution theory that accounts for excluded-volume…
