Journal ArticleDOI
Heat release rate markers for premixed combustion
TL;DR: In this paper, the validity of the commonly used flame marker for heat release rate (HRR) visualization, namely the rate of the reaction OH+CH 2 O⇔ HCO+H 2 O is re-examined.
Journal ArticleDOI
A 5-step reduced mechanism for combustion of CO/H2/H2O/CH4/CO2 mixtures with low hydrogen/methane and high H2O content
TL;DR: ZMN and NS acknowledge the funding through the Low Carbon Energy University Alliance Programme supported by Tsinghua University, China as mentioned in this paper, and also like to acknowledge the educational grant through the A.G. LeventisFoundation.
Journal ArticleDOI
Direct mapping from LES resolved scales to filtered-flame generated manifolds using convolutional neural networks
TL;DR: In this paper, a unified modelling framework for all unresolved terms in the filtered progress variable transport equation in large-eddy simulations of turbulent premixed flames is proposed, using convolutional neural networks.
Journal ArticleDOI
Progress Variable Variance and Filtered Rate Modelling Using Convolutional Neural Networks and Flamelet Methods
TL;DR: A purely data-driven modelling approach using deep convolutional neural networks is discussed in the context of Large Eddy Simulation (LES) of turbulent premixed flames, demonstrating with success for both the sub-grid scale progress variable variance and the filtered reaction rate.
Journal ArticleDOI
