A numerical study of planar detonations.
(Departamento de Mecánica, 2010-11-29)
A one dimensional numerical study on the build-up and propagation of planar detonation waves in H2 and Air combustibles mixtures is presented. To describe the motion of a traveling detonation the unsteady Euler equations ...
rhoCentralRfFoam: An OpenFOAM solver for high speed chemically active flows – Simulation of planar detonations
(Elsevier Science, 2017-10)
A new solver developed within the framework of OpenFOAM 2.3.0, called rhoCentralRfFoam which can be interpreted like an evolution of rhoCentralFoam, is presented. Its use, performing numerical simulations on initiation and ...
A numerical study on the impact of chemical modeling on simulating methane-air detonations
This article presents a study concerning the influence of chemical kinetic models on the generation and evolution of methane-air planar detonations. The open source solver rhoCentralRfFoam is applied to perform all numerical ...
Stability of cosmological detonation fronts
(American Physical Society, 2014-04)
The steady state propagation of a phase transition front is classified, according to hydrodynamics, as a deflagration or a detonation, depending on its velocity with respect to the fluid. These propagation modes are further ...
Two-dimensional numerical simulations of detonation cellular structures in H2–O2–Ar mixtures with OpenFOAM®
(Pergamon-Elsevier Science Ltd, 2017-09)
In the present work, the solver rhoCentralRfFoam, developed using the finite volume framework provided by OpenFOAM®, is employed to perform numerical simulations of two-dimensional detonations. This solver uses the central ...
