Fuxin Leather Base Worker Building Evacuation Staircase Positive Pressure Ventilation Simulation Research Using CFD Simulation

FuXin leather base is a key project that our city introduces, and is the impotantindustry pillar to drive FuXin’economy grow, the city government leaders attach greatimportance to the project, and pay high attention to to the project, builds, and checks.FuXin leather base staff multifunctional building is the key high floor bulding of theproject. the building gathers market, hotel, apartment house togeher and two floorsunderground,17floors on the ground, building’s structure is complicated, has completefuntion and fire control designs is strict.After the building is put in use when the utility area personnel is concentrated,once conflagration happened, the dispersed stair half will become main fleeing for one’slife passage. Bring about death’s as a result of counting in the conflagration,90%’sdeath is that the cigarette gas brings about because the conflagration is hit by creation’s,The synthetical building of Fu Xin City leather base staff and worker evacuates stair halfthe eject smoke condition under various condition, alternative one kind is the mostsuitable, eject smoke speed is the quickest therefore the thesis is main whileconflagration happened research,can ensure dispersed personnel row cigarette waymost. Be the thesis research direction.Being put into use being intimidating the technology being ventilated with is thatthe stair half cigarette makes the up-to-date technology that blowoff controls angry. Thatthe stair half is controlling a conflagration now and then be ventilated is whether or notproper, personnel’s survival probability rescues direct effect of general to fleeing forone’s life in the conflagration within the building in order the sum fighting fire gainingtime. The thesis has analysed the mobile factor affecting synthetical building of Fu XinCity leather base staff and worker cigarette gas infestation in depth, has includedchimney effect, natural wind, thermal expansion, buoyance, air-conditioning systemand electric elevator piston effect etc. among them, after having discussed nowavailable cigarette with method making the principle controlling measure’s angry. Onabroad entity experiment basis, adopt the mature conflagration to simulate softwareFDS estimating that the synthetical building of Fu Xin City leather base staff and workerevacuates stair half various index being ventilated in fair pressure of conflagration.Think that the dispersed stair half of reference is controlling entity experiment beingin progress in raw building being ventilated, FDS assists usage building model softwarePyrosim having built3D model of dispersed stair half and fire outbreaking out storey,the source is parametric by being changing, get suppositional environment evacuating after the stair half is made inroads on by cigarette gas. Have set up four kinds finally onthe basis here, being controlling ventilation way, have come to analyse four kindsvalidity being controlling ventilation way, have reached optimum be controllingventilation way after comparison by the experiment carrying out FDS a train of.
