Statistical analysis of the velocity and scalar fields in reacting turbulent wall-jets
, 2015 The concept of local isotropy in a chemically reacting turbulent wall-jet flow is addressed using direct numerical simulation (DNS) data. Different DNS databases with isothermal and exothermic reactions are examined.

Flow Field of Turbulent Premixed Combustion in a Cyclone-Jet Combustor
Journal of Thermal Science and Technology, 2007 The flow field in highly turbulent premixed combustion has been examined, using a cyclone-jet combustor. The shear-strain rate is obtained by PIV system. Results show that, in combustion field, mean axial velocity does not decay along center axis and RMS

Applications in Energy and Combustion ScienceLarge eddy simulation (LES) is an important tool for studying turbulent spray combustion and developing next-generation combustion devices. In LES, the subgrid-scale (SGS) stress needs to be modeled with the closure models.

Large Eddy Simulation of a Swirl-Stabilized Pilot Combustor from Conventional to Flameless Mode
Journal of Combustion, 2016 This paper investigates flame and flow structure of a swirl-stabilized pilot combustor in conventional, high temperature, and flameless modes by means of a partially stirred reactor combustion model to provide a better insight into designing lean ...

Premixed Turbulent Combustion in Opposed Streams
, 1992 Premixed turbulent combustion in opposed streams has been studied experimentally by the use of two component laser doppler aneomometry. This flow geometry is part of a class of stagnating flows used to study turbulent combustion in recent years. It does not involve any surface near the flames because of the flow symmetry thus circumventing many of the ...

A Generalised Series Model for the LES of Premixed and Non-Premixed Turbulent Combustion
EnergiesIn this study, the generality and prediction accuracy of a generalised series model for the large eddy simulation of premixed and non-premixed turbulent combustion is explored. The model is based on the Taylor series expansion of the chemical source term
