Sparse Data Structures for Efficient State-to-State Kinetic Simulations
Ayoub Gouasmi, Scott Murman
Higher-fidelity entry simulations can be enabled by integrating finer thermo-chemistry models into compressible flow physics. One such class of models are State-to-State (StS) kine…
Entropy-Stable Schemes in the Low-Mach-Number Regime: Flux-Preconditioning, Entropy Breakdowns, and Entropy Transfers
Ayoub Gouasmi, Karthik Duraisamy, Scott M. Murman
Entropy-Stable (ES) schemes, specifically those built from [Tadmor \textit{Math. Comput.} 49 (1987) 91], have been gaining interest over the past decade, especially in the context…
A minimum entropy principle in the compressible multicomponent Euler equations
Ayoub Gouasmi, Karthik Duraisamy, Scott M. Murman +1
In this work, the space of admissible entropy functions for the compressible multicomponent Euler equations is explored, following up on [Harten, \textit{J. Comput. Phys.}, 49 (1),…
Formulation of Entropy-Stable schemes for the multicomponent compressible Euler equations
Ayoub Gouasmi, Karthik Duraisamy, Scott Murman
In this work, Entropy-Stable (ES) schemes are formulated for the multicomponent compressible Euler equations. Entropy-conservative (EC) and ES fluxes are derived. Particular attent…
On entropy stable temporal fluxes
Ayoub Gouasmi, Karthik Duraisamy, Scott Murman
Entropy-stable (ES) schemes have gained considerable attention over the last decade, especially in the context of turbulent flow simulations using high-order methods. While promisi…
Entropy Conservative Schemes and the Receding Flow Problem
Ayoub Gouasmi, Scott Murman, Karthik Duraisamy
This work delves into the family of entropy conservative (EC) schemes introduced by Tadmor. The discussion is centered around the Euler equations of fluid mechanics and the recedin…
A Priori Estimation Of Memory Effects In Coarse-Grained Nonlinear Systems Using The Mori-Zwanzig Formalism
Ayoub Gouasmi, Eric Parish, Karthik Duraisamy
Reduced Order Models (ROMs) of complex, nonlinear dynamical systems often require closure, which is the process of representing the contribution of the unresolved physics on the re…
