On the Rapid Estimation of Permeability for Porous Media Using Brownian Motion Paths
Chi-Ok Hwang, James A. Given, Michael Mascagni
We describe two efficient methods of estimating the fluid permeability of standard models of porous media by using the statistics of continuous Brownian motion paths that initiate…

An Efficient Modified "Walk On Spheres" Algorithm for the Linearized Poisson-Boltzmann Equation
Chi-Ok Hwang, Michael Mascagni
A discrete random walk method on grids was proposed and used to solve the linearized Poisson-Boltzmann equation (LPBE) \cite{Rammile}. Here, we present a new and efficient grid-fre…
