Numerical Simulation of the Influence of Fire Source Location on Fires Smoke Flow in Deep Well
This paper explored the influence of different fire source locations on the severity of fire in deep well vertical space,and constructed a deep well vertical space model.Through numerical simulation,the heat release rate of the fire source and the distance between the fire source and the wall on the smoke flow,smoke temperature,and velocity in deep well vertical spaces were analyzed.The results indicated that in vertical deep well spaces,the fire plume flow is easily restricted by walls.When the fire source approaches a single wall,the flame plume will tilt towards the near wall surface.Under the same time con-ditions,the closer the fire source is to a single wall,the higher the height and temperature of the smoke directly above the fire source,and the faster the upward flow speed of the smoke.Based on the simulation results,a formula is used to fit the relation-ship between plume temperature and depth,as well as the distance between the fire source and the wall.
