Data-assisted combustion simulations with dynamic submodel assignment using random forests [PDF]
Combustion and Flame 227 (2021) 172-185, 2020 In this investigation, we outline a data-assisted approach that employs random forest classifiers for local and dynamic combustion submodel assignment in turbulent-combustion simulations. This method is applied in simulations of a single-element GOX/GCH4 rocket combustor; a priori as well as a posteriori assessments are conducted to (i) evaluate the ...

Beyond MHz image recordings using LEDs and the FRAME concept
Scientific Reports, 2020 Many important scientific questions in physics, chemistry and biology rely on high-speed optical imaging techniques for their investigations. These techniques are either passive, relying on the rapid readout of photoactive elements, or active, relying on

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 ...

Reduction of nitric oxide emissions from a combustor [PDF]
, 1980 A turbojet combustor and method for controlling nitric oxide emissions by employing successive combustion zones is described. After combustion of an initial portion of the fuel in a primary combustion zone, the combustion products of the primary zone are

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
