1、参数 描述 备注 Heat Release Rate(热释放率)The heat release rate per unit area of this burner.Mass Loss Rate The mass loss rate per unit area of this burner.Ramp-Up Time(增加,上升时间)At the beginning of the simulation,this surface will not beburning.This field allows you to describe how the heat releaseramps up fro
2、m ambient to the specified value.(暂时不明白)Extinguishing Coefficient(熄灭系数)This parameter governs the suppression of the fire by water.(喷淋系统)Surface Temperature The surface temperature of this burner.Convective Heat Flux(对流热通量)The heat flux per unit area at the surface Emissivity This parameter controls
3、 how the surface radiates heat.Usinga value of 1.0 makes this surface a black body.Lower valuesincreate the amount of radiated heat.参数 描述 备注 Emit Particles Enable this option to emit particles from the surface.Particle Type Select a particle to emit.Number of Particles per Cell Controls the number o
4、f particles inserted per second.A valueof 1 will insert one particle per cell per second.Mass Flux For particles that have mass,this option provides an alternate 水 Layered(分层)Layered surfaces are composed of one or more material definitions.Materials include solid andliquid substances such as concre
5、te(混泥土),pine(松木),and ethanol(乙醇).Backing The backing of a surface is the boundary condition behindthe surface.The default value,Air Gap represents an air gap,Exposed will allow the surface to transfer heat into the space behind the wall,and Insulated prevents any heat loss from the back of the mater
6、ial.Material Composition Within a layer(row),you can specify multiple materials based on mass fraction.For example,to specify a layer that is just brick,type 1.0 BRICK(assuming you have created a material called BRICK).To specify a layer of wet brick,you could enter 0.95 BRICK;0.05 WATER.Each materi
7、al is separated by a semi-colon.Porous(能穿透)The property is generally used to create a fan using a thin obstruction.Enable Leakage This option allows you to select two pressure zones for leakage across the surface.Air Leak Air leak surfaces can be used to create a permeable barrier between two pressu
8、re zones.The porous option is available to allow air movement to occur across this obstructions using this surface.Adding Textures to Surfaces You can add textures to surfaces to increase the realism of your model.Some default textures are provided or you can import your own.The Room Fire example de
9、monstrates using a wood texture for a pine floor and hanging a picture on a wall.Your textures will be automatically displayed in PryoSim;to display textures in Smokeview,select Textures on the Show/Hide menu.To define a texture:醇能穿透漩涡楼梯使用状况模拟门在某个时间打开模拟窗在某个时间打开模拟通风系统在某个时间开启测量固体的温度和密度这固体表面必须定义为有热传导的如
