Global random walk for one-dimensional one-phase Stefan-type moving-boundary problems: Simulation results

Nicolae Suciu, Surendra Nepal, Yosief Wondmagegne +2

This work presents global random walk approximations of solutions to one-dimensional Stefan-type moving-boundary problems. We are particularly interested in the case when the movin…

Numerical Exploration of Nonlinear Dispersion Effects via a Strongly Coupled Two-scale System

Surendra Nepal, Vishnu Raveendran, Michael Eden +2

The effective, fast transport of matter through porous media is often characterized by complex dispersion effects. To describe in mathematical terms such situations, instead of a s…

Strongly Coupled Two-scale System with Nonlinear Dispersion: Weak Solvability and Numerical Simulation

Vishnu Raveendran, Surendra Nepal, Rainey Lyons +2

We investigate a two-scale system featuring an upscaled parabolic dispersion-reaction equation intimately linked to a family of elliptic cell problems. The system is strongly coupl…

Random walks and moving boundaries: Estimating the penetration of diffusants into dense rubbers

Surendra Nepal, Magnus Ogren, Yosief Wondmagegne +1

For certain materials science scenarios arising in rubber technology, one-dimensional moving boundary problems (MBPs) with kinetic boundary conditions are capable of unveiling the…

Analysis of a fully discrete approximation to a moving-boundary problem describing rubber exposed to diffusants

Surendra Nepal, Yosief Wondmagegne, Adrian Muntean

We present a fully discrete scheme for the numerical approximation of a moving-boundary problem describing diffusants penetration into rubber. Our scheme utilizes the Galerkin fini…

Error estimates for semi-discrete finite element approximations for a moving boundary problem capturing the penetration of diffusants into rubber

Surendra Nepal, Yosief Wondmagegne, Adrian Muntean

We consider a moving boundary problem with kinetic condition that describes the diffusion of solvent into rubber and study semi-discrete finite element approximations of the corres…

A moving boundary approach of capturing diffusants penetration into rubber: FEM approximation and comparison with laboratory measurements

Surendra Nepal, Robert Meyer, Nils Hendrik Kröger +4

We propose a moving-boundary scenario to model the penetration of diffusants into dense and foamed rubbers. The presented modelling approach recovers experimental findings related…
