Entropy dissipative high order schemes for a hyperbolic model of two-layer thin film flow
Rahul Barthwal, Philipp Öffner, Chetan Singh +1
In this article, we develop high-order, entropy-dissipative schemes for a hyperbolic system of conservation laws describing the first-order dynamics of two-layer thin-film flows of…
A structure-preserving implicit-explicit method for a hyperbolic approximation of fourth-order PDEs
Rahul Barthwal, Rahuldev Ghorai
We introduce a novel structure-preserving numerical method for a first-order hyperbolic approximation system, which approximates the solutions of general fourth-order partial diffe…
Riemann invariant-based alternative WENO scheme for a two-layer thin film model
Biswarup Biswas, Rahul Barthwal, Rakesh Kumar
In this article, we develop a multi-dimensional two-layer thin film model extending the thin film model proposed in \cite{barthwal2025hyperbolic}. The model considered in \cite{bar…
