EXPLOSION BEHAVIOR OF N-DODECANE IN AIR

The explosion behavior of n-dodecane has been investigated through experiments performed in a closed 5-l cylindrical vessel by varying the concentration of (vaporized) fuel in air at two different initial temperatures - 130°C and 160°C. From the recorded pressure-time histories, the maximum explosion pressure has been quantified. Chemical equilibrium calculations were also run to compute the adiabatic pressure. It has been found that, prior to feeding air and igniting the fuel/air mixture, the n-dodecane injected into the explosion vessel undergoes pyrolysis phenomena that interfere with combustion, thus affecting the performed measurements.
