To calculate soot source terms a new detailed kinetic soot model is applied to study the formation and oxidation of soot particles in turbulent flames. The model is based on a detailed description of the chemical and physical processes leading to the formation of soot. It can be subdivided into the growth of polycyclic aromatic hydrocarbons (PAHs) in the gas phase reactions and the processes of...

Introduction Chemically reacting flows are of increasing importance to NASA's terrestrial and space missions. In cases where the flow geometry is complex, which includes most practical devices, ability to utilize overset grids greatly enhances NASA's ability to accurately model the flow physics. The OVERFLOW code is therefore an ideal platform for implementing chemical modeling capability. This...

In this study, we show numerical predictions of the Zimont and Peter's turbulent flame speed models for low-swirl Methane/Air/Hydrogen flames [1]. These are contained as default options within ANSYS Fluent Premixed reaction model. Two distinct simulation tasks part present study – non-reacting reacting flows, with three different methane mixtures in compositions added 0, 40 60% hydrogen. The re...

This study is concerned with the numerical analysis, formulation, programming and computation of steady, 3D conservation equations of reacting laminar flow heat and mass transfer in ducts of arbitrary cross-sections. The non-orthogonal boundary-fitted coordinate transformation method is applied to the Cartesian form of overall-continuity, momenta, energy and species-continuity equations, parabo...

Recent developments in deep learning have brought many inspirations for the scientific computing community and it is perceived as a promising method accelerating computationally demanding reacting flow simulations. In this work, we introduce DeepFlame, an open-source C++ platform with capabilities of utilising machine algorithms pre-trained models to solve reactive flows. We combine individual ...
