Combustion characteristics of gel fuels
An experimental investigation of the combustion phenomena of gel fuel droplets was conducted using a computerized video system. The ignition and combustion processes were viewed and recorded while the droplet and flame temperatures were measured simultaneously. A parametric investigation was conducted to evaluate the effect of the gellant content in the fuel, the ambient pressure and the oxygen mass fraction on the droplet burning rate. The heat of vaporization of gel fuels was measured and was found to increase with increasing the gellant content. The experimental results correlate well with the d(2)-law and indicate that gels burn similar to liquids, however at lower burning rates. Ignition of gels was more difficult in comparison to liquids, especially at relatively high pressures.
