Large eddy simulation of unsteady combustion

Measurements and LES calculations of turbulent premixed flame propagation past repeated obstacles

“…SGS modelling approaches that are seen as alternatives to flamelets include the filtered density functions (FDF) [15], the conditional moment closure [16] and the linear eddy model (LEM) [17]. Each of these approaches suffers from different limitations that are currently the subject of intense research.…”

An assessment of large eddy simulations of premixed flames propagating past repeated obstacles

“…Several modelling approaches such as flame surface density (FSD) [7&8], flame tracking technique (G-equation) [9][10][11], artificially thickened modelling [12] and probability density function (PDF) [13] where the rate of combustion is expressed as a function of a reaction progress variable and the filter width. The FSD modelling approach [14] is considered in the present study and efforts are made to calculate the model coefficient by employing a sub-model.…”

An Efficient Numerical Model of Pulsating Combustion and Its Experimental Validation

“…from one-dimensional approaches [8][9][10][11] to three-dimensional models using Large Eddy Simulation [12] [13]. Experimental studies have been also carried out by performing time-resolved measurements of flow field, temperature and heat release inside pulse combustors [14][15][16].…”
