Numerical investigations on tri-fuel chemical kinetics of hydrogen + Methane +LPG/air mixtures using reduced skeletal mechanism
TL;DR: In this article , the combustion and ignition characteristics of three fuels with different reactivities have been investigated by a reduced chemical kinetic model, with the help of TF blends of LPG + CH4+H2 at the pressure and temperature range of 1-20 atm and 900-2000 K, respectively.

Heat Release Rate Markers for Highly Stretched Premixed CH$_{4}$/Air and CH$_{4}$/H$_{2}$/Air Flames
TL;DR: In this paper, the spatial distribution of heat release rate (HRR) profiles is quantified for a spherically expanding flame (SEF) and a Bunsen flame with a high negative stretch rate at the flame tip.

Analysis of the explosion behaviour of wheat starch/pyrolysis gases hybrid mixtures through experimentation and CFD-DPM simulations
TL;DR: In this article, the authors performed an exhaustive analysis of the explosion severity of wheat starch/pyrolysis gases hybrid mixtures in the context of the 20-L Sphere Test and to determine how severe hybrid mixture explosions can be when compared to one phase explosions.

Reconstruction model for heat release rate based on artificial neural network
TL;DR: In this paper, a novel artificial neural network (ANN) approach was adopted to build the mapping relationship between the combustion heat release rate and the measurable chemiluminescent species.

Examination of an oscillating flame in the turbulent flow around a bluff body with large eddy simulation based on the probability density function method
TL;DR: In this article, a large-eddy simulation framework for the simulation of oscillating flames in practical flow configurations is described. But, it was found that formaldehyde-based measures do not appropriately reproduce the amplitude and phase of the total heat release rate, and a significantly improved correlation was achieved by employing the product of the mass fractions of molecular oxygen (O2) and the ketenyl radical (HCCO) as a means of characterising the variation of the temperature variation.

Vortex-driven acoustically coupled combustion instabilities
TL;DR: In this article, the authors investigated low-frequency vortex-driven combustion instability in the case of a multiple inlet combustor with dump and showed that lowfrequency instabilities are acoustically coupled and occur at the eigenfrequencies of the system.
