Journal of engineering physics and thermophysics Vol. 94, № 3. P. 753-764Abstract: A mathematical model of combustion of an aerosol of an aluminum nanopowder suspension in kerosene is presented, in which the state parameters of aerosol are determined by solving the system of energy conservation equations of gas, droplets, and particles, mass conservation equations of gas suspension components, and of the equations of motion of droplets and particles. The rate of oxidation of aluminum nanoparticles and the associated rate of heat release have been determined, as well as the dependences of the velocity of combustion front propagation in the aerosol on the mass concentrations of kerosene and aluminum nanopowder and on the initial aerosol temperature.
