Combustion Instability of a Multi-injector Rocket Engine Using the Flamelet Progress Variable Model [PDF]
arXiv, 2021 The combustion instability is investigated computationally for a multi-injector rocket engine using the flamelet progress variable (FPV) model. A C++ code is developed based on OpenFOAM 4.0 to apply the combustion model. Flamelet tables are generated for methane/oxygen combustion at the background pressure of $200$ bar using a 12-species chemical ...

On the Possibility of Combustion of Neutrons into Strange Quark Matter [PDF]
Phys.Lett.B639:232-236,2006, 2005 It is shown that a conversion of neurons into strange quark matter in neutron stars is possible by means of a combustion process with a well-defined front. Conditions for the realization of a specific combustion mode, whether deflagration, detonation, or fast combustion, are discussed for several forms of the equations of state of neutron and strange ...

Well-posed problem for a combustion model in a multilayer porous medium [PDF]
arXiv, 2023 Combustion occurring in porous media has various practical applications, such as in in-situ combustion processes in oil reservoirs, the combustion of biogas in sanitary landfills, and many others. A porous medium where combustion takes place can consist of layers with different physical properties. This study demonstrates that the initial value problem
