Class Bflame spread rating 26-75 Class Cflame spread rating 76-200 Class Dflame spread rating 201-500 Class Eflame spread rating over 500 The installation of a complete automatic sprinkler system in structures having these interior finish materials modifies the fire hazard risk. ...
1) flame spread index = flame-spread index 火焰蔓延指数2) flame spread 火焰蔓延 1. In a bench scale tunnel,the flame spread length on a PVC conveyor belt was calculated with the above ignition criterion. 利用此温度判据,对输送带在实验巷道中火焰蔓延情况进行了数值模拟。 2. Using little ...
flame-spread index A numerical designation, applied to a building material, which is a comparative measure of the ability of the material to resist flaming combustion over its surface; the rate of flame travel, as measured under the applicable ASTM test, in which a selected species of untreated...

A computational model of three-dimensional, time-dependent flame spread in a microgravity environment is presented. The solid is assumed to be a thermally thin, pyrolysing cellulosic sheet. The gas-phase model includes the full Navier-Stokes equations with density and pressure variations and a six...
A computational procedure for analysis of the melting, burning and flame spread of polymers under fire conditions is presented. The method, termed particle finite element method (PFEM), combines concepts from particle-based techniques with those of the standard finite element method (FEM). The key...

It is also found that the continuous flame is not a characteristic length for the heat transfer to the unburnt fuel and is not really appropriate to define flame height in upward flame spread. 展开 关键词: upward flame spread steady wall flame flame height definition numerical model ...
Flame spread over thin fuels in actual and simulated microgravity conditions Most previous research on flame spread over solid surfaces has involved flames in open areas. In this study, the flame spreads in a narrow gap, as occurs i...
