Analysis of the Large Urban Fire Environment,

Abstract

An analysis describing the high temperature and velocity environment of a large urban area fire is presented. The boundary value problem treats the burning region in detail. A novel prescription of the boundary conditions at the fire periphery allows the burning-region analysis to be uncoupled from analyses of the free-convection column and the far field. The relationship between burning rate, buoyancy, pressure gradients, and the creation of high velocity fire winds is described. Sample results simulate the burning-region environment for the 1943 Hamburg firestorm. (Author)
