β¦ Synopsis
A ventilation parameter is defined in terms of the availability of oxygen with respect to the stoichiometric combustion requirements. Pagni's flame height relations for forced air flow conditions have been used to quantify the variations in the fire properties with ventilation. For the experimental conditions used, relations have been established between flame height and ventilation parameter, oxygen consumption in the combustion process, combustion efficiency, and generation efficiencies of various chemical compounds.

An experimental setup has been designed and built to study, at a laboratory scale, the behavior of a wall fire in a semi-confined compartment both in naturally ventilated and vitiated (combustion products) atmospheres. A diffusion flame is stabilized along a vertical porous flat burner located at t
