摘要: In this study, simulations of propagating turbulent premixed deflagrating flames past built in solid obstructions a laboratory scale explosion chamber has been carried out with the Large Eddy Simulation (LES) technique. The design allows for up to three baffle plates be positioned path flame, rendering different configurations, hence generating turbulence and modifying structure reaction zone. Five important configurations are studied understand feedback mechanism between flame-flow interactions burning rate. LES, sub-grid (SGS) rate should accounted by an appropriate model that can essentially capture physics. present work using flame surface density (FSD) influence flow on propagation as result in-built is also examined. impact number position such baf...
