Abstract
The paper presents the results of numerical simulation of the process of molecular hydrogen production during the combustion of aluminum nanopowder in steam. The calculations are carried out on the basis of a previously developed combustion model of an ensemble of aluminum nanoparticles in steam. As a result of calculations, the time histories of mixture temperature and concentrations of components, including molecular hydrogen, are found at different values of the initial conditions (temperature, radius of aluminum particles and the presence of an oxide film on them, and the ratio of initial concentrations of aluminum and water). The effect of small oxygen additives on the combustion process has also been studied. The obtained data allow one to find conditions for achieving the maximum degree of conversion of steam into molecular hydrogen at optimal thermophysical parameters of combustion products.
