Collocation Finite Element Method for the Fractional Fokker–Planck Equation

International Journal for Numerical Methods in Fluids, Volume 97, Issue 3, Page 224-232, March 2025.
This study explores approximate solutions for fractional Fokker–Planck equations using general finite element schemes developed via the collocation finite element method with trigonometric quintic B‐spline basis functions. It validates these methods on two fundamental problems and compares numerical results, including L2$$ {L}_2 $$ and L∞$$ {L}_{\infty

A Relaxation Scheme for the Simulation of Two‐Phase Flows With Inaccessible Pore Volume in Polymer Flooding

International Journal for Numerical Methods in Fluids, Volume 97, Issue 3, Page 244-266, March 2025.
We design of a relaxation scheme to cope with instabilities intrinsic to a possibly non‐hyperbolic system of conservation laws arising from polymer injection models. We improve the robustness via control of positivity and peak amplitudes for most severe closure laws representing inaccessible pore volumes effect.

Stability of N‐front and N‐back solutions in the Barkley model

GAMM-Mitteilungen, Volume 48, Issue 1, March 2025.
ABSTRACT In this article, we establish for an intermediate Reynolds number domain the stability of N$$ N $$‐front and N$$ N $$‐back solutions for each N>1$$ N>1 $$ corresponding to traveling waves, in an experimentally validated model for the transition to turbulence in pipe flow proposed in [Barkley et al., Nature 526(7574):550‐553, 2015]. We base our

A nonlinear characterization of stochastic completeness of graphs

Mathematische Nachrichten, Volume 298, Issue 3, Page 925-943, March 2025.
Abstract We study nonlinear Schrödinger operators on graphs. We construct minimal nonnegative solutions to corresponding semilinear elliptic equations and use them to introduce the notion of stochastic completeness at infinity in a nonlinear setting. We provide characterizations for this property in terms of a semilinear Liouville theorem.

Fusion‐Based Constitutive Model (FuCe): Toward Model‐Data Augmentation in Constitutive Modeling

International Journal of Mechanical System Dynamics, Volume 5, Issue 1, Page 86-100, March 2025.
ABSTRACT Constitutive modeling is crucial for engineering design and simulations to accurately describe material behavior. However, traditional phenomenological models often struggle to capture the complexities of real materials under varying stress conditions due to their fixed forms and limited parameters.
