An analytic probability density function for partially premixed flames with detailed chemistry [PDF]
Physics of Fluids 33, 035117 (2021), 2021 Laminar premixed flame profiles of methane/air free flames and strained flames at different fuel/air ratios and strain rates are analysed using detailed chemistry with Lewis numbers equal to one. It is shown that the detailed chemistry flame profiles of progress variables CO2+CO and H2O+H2 in canonically stretched coordinates can be fitted accurately ...

Automatic differentiation in quantum chemistry with an application to fully variational Hartree-Fock [PDF]
ACS Cent. Sci, 4, 559 (2018), 2017 Automatic Differentiation (AD) is a powerful tool that allows calculating derivatives of implemented algorithms with respect to all of their parameters up to machine precision, without the need to explicitly add any additional functions. Thus, AD has great potential in quantum chemistry, where gradients are omnipresent but also difficult to obtain, and

A load balanced chemistry model with analytical Jacobian for faster reactive simulations in OpenFOAM [PDF]
arXiv, 2021 In this study, we introduce a novel open-source chemistry model for OpenFOAM to speed-up the reactive computational fluid dynamics (CFD) simulations using finite-rate chemistry. First, a dynamic load balancing model called DLBFoam is introduced to balance the chemistry load during runtime in parallel simulations.

Implementation of chemistry in the Athena++ code [PDF]
arXiv, 2023 Chemistry plays a key role in many aspects of astrophysical fluids. Atoms and molecules are agents for heating and cooling, determine the ionization fraction, serve as observational tracers, and build the molecular foundation of life. We present the implementation of a chemistry module in the publicly available magneto-hydrodynamic code Athena++.
