Aluminum Powder/Water Reaction Ignited by Electrical Pulsed Power

Abstract

The effectiveness of the electrical pulsed power technique in driving aluminum-water reactions has been studied. The reactant was prepared by mixing, in the stoichiometric ratio, fine aluminum powder (the fuel) and water (the oxidizer). The electrical energy was delivered to the reactant through an ignition wire embedded in it. The primary objective of the study was to maximize the energy efficiency, which is defined as the ratio of the chemical energy output from the reaction to the electrical energy input. The energy efficiency depends critically on the electrical circuit parameters, physical parameters of the metal fuel powder, and geometrical arrangements of the reactant. Under an optimized set of experimental variables, the energy efficiency exceeds 100.... Aluminum, Hydrogen generation, Pulsed power technique
