Boosting the Accuracy of Finite Difference Schemes via Optimal Time Step Selection and Non-Iterative Defect Correction
Kevin T. Chu
In this article, we present a simple technique for boosting the order of accuracy of finite difference schemes for time dependent partial differential equations by optimally select…
Surface Conservation Laws at Microscopically Diffuse Interfaces
Kevin T. Chu, Martin Z. Bazant
In studies of interfaces with dynamic chemical composition, bulk and interfacial quantities coupled via surface conservation laws of excess surface quantities. While this approach…
A Direct Matrix Method for Computing Analytical Jacobians of Discretized Nonlinear Integro-differential Equations
Kevin T. Chu
In this pedagogical article, we present a simple direct matrix method for analytically computing the Jacobian of nonlinear algebraic equations that arise from the discretization of…
A Variational Level Set Approach for Surface Area Minimization of Triply Periodic Surfaces
Youngjean Jung, Kevin T. Chu, Salvatore Torquato
In this paper, we study triply periodic surfaces with minimal surface area under a constraint in the volume fraction of the regions (phases) that the surface separates. Using a var…
Nonlinear electrochemical relaxation around conductors
Kevin T. Chu, Martin Z. Bazant
We analyze the simplest problem of electrochemical relaxation in more than one dimension - the response of an uncharged, ideally polarizable metallic sphere (or cylinder) in a symm…
Electrochemical Thin Films At and Above the Classical Limiting Current
Kevin T. Chu, Martin Z. Bazant
We study a model electrochemical thin film at dc currents exceeding the classical diffusion-limited value. The mathematical problem involves the steady Poisson-Nernst-Planck equati…
