Large Eddy Simulation of Transient Combustion and Sootrecession in the Ecn Spray a and D Flames

“…Prior to analyzing the soot recession, the soot formation and oxidation processes during the quasi-steady state (QSS) is examined. The examination can be found in authors' previous study [46,47], in which the soot mass and distribution during the QSS were reasonable captured. In the present study, the soot recession refers to the phenomenon where soot forms closer to the injector region AEOI [5].…”

Influence of the primary components of the high-speed train on fire heat release rate

“…During a fire, the flow of smoke is a three-dimensional, unsteady, and compressible turbulent flow. The Fire Dynamics Simulator (FDS, version 6.7.4) [14][15][16][17] program is used to simulate the train fire (a computational fluid dynamics (CFD) model of fire-driven fluid flow), and the turbulent flow of smoke is solved by the large eddy simulation (LES) [18][19][20]. The governing equations are shown below [21][22][23][24]: Mass conservation equation…”
