| Abstract Scope |
This work describes the initial results of a study to determine the potential of a 1:1 Mg:carbon ratio slurry-fuel consisting of magnesium hydride (MgH2) and a surrogate fuel. Magnesium oxide (MgO) reacts in the atmosphere with CO2 to form magnesium carbonate (MgCO3) or magnesium bicarbonate (Mg(HCO3)) thus capturing carbon. When comparing the surrogate fuel chosen for this study, n-dodecane (n-C12H26), MgH2 has ~33% less energy/mass but ~28% higher energy/volume. Using Cantera, models compare the thermal performance of the slurry to pure n-C12H26. The models show that relative to energy content, the slurry requires 2-5% less fuel than n-C12H26 to reach the same temperature. The Breguet equation estimates that the slurry could achieve 8% higher aircraft range than the same volume of n-C12H26. Droplet experiments observed this fuel’s combustion characteristics and MgO combustion product morphology. The presentation will also discuss implications for engine and airframe design. |
