Abstract

The research program comprises two different problems: open fires and transport of firebrands, which will be treated separately. Open Fires The investigation on open fires has been directed towards the study of the basic laws governing the process, which relate the physico-chemical properties of the fuel with the observable characteristics of a fire, such as flame temperature, flame size, convection column, radiant energy, etc A fire is a very complex process. Its study is being conducted by carrying out a series of measurements in a research facility and by studying theoretically some partial processes which are part of the over-all process. A research facility has been prepared in a tower of a test stand for aircraft engines which has been conditioned to that purpose. The research facility comprises several cylindrical open vessels (burners) of different diameters, for studying the fires produced by several types of fuels. The fuel is kept at a constant level in the burners and the fuel consumption is measured by means of a constant-pressure volumetric system. Thermocouples and pressure probes are placed in and around the fire to measure temperatures, and velocities of the gases. Burning rates, flame temperatures, flame sizes, fuel temperatures, gas velocities, etc, are being measured for gasoline, kerosene and for dioxane-water mixtures. The dioxane is a fuel which mixes with water in all proportions and it has a similar boiling temperature than that of the water. Therefore, dioxane-water mixtures keep a constant composition during combustion and by varying the amount of water of the mixture it is possible to change in a continuous form the properties of the fire. Some theoretical problems in connection with open fires are also being studied, such as motion and mixing of a hot gas stream with air and diffusion flames considering body forces. All experimental and theoretical studies are progressing satisfactorily and several results are given in the paper.
