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…
Arbitrary Order Solutions for the Eikonal Equation using a Discontinuous Galerkin Method
David Flad, Aniruddhe Pradhan, Scott Murman
We provide a method to compute the entropy-satisfying weak solution to the eikonal equation in an arbitrary-order polynomial space. The method uses an artificial viscosity approach…
Parameter Estimation for RANS Models Using Approximate Bayesian Computation
Olga A. Doronina, Scott M. Murman, Peter E. Hamlington
We use approximate Bayesian computation (ABC) to estimate unknown parameter values, as well as their uncertainties, in Reynolds-averaged Navier-Stokes (RANS) simulations of turbule…
Analysis of high-order velocity moments in a strained channel flow
S. V. Poroseva, S. M. Murman
In the current study, model expressions for fifth-order velocity moments obtained from the truncated Gram-Charlier series expansions model for a turbulent flow field probability de…
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),…
