Abstract
A mathematical model of time-dependent, three-dimensional buoyant convection produced by a room fire is presented. The basic equations, derived earlier by the authors, are for inviscid, non-heat-conducting flows of variable density dirven by a prescribed heat source representing a fire. The nondissipative nature of these equations (infinite Grashof number) implies that only large scale features of the motion can be described. No turbulence model is employed, but large eddy motions can be determined. Variable density is required to describe large temperature excursions produced in a fire.
