    Processes of combustion of aluminium particles in gas discharge

    No full text
    The regime of combustion of aluminium microparticles involving oxidant molecules is analyzed if heating of these particles leads to evaporation of aluminium atoms from the particle surface which form aluminium nanoclusters and they, in turn, partake in chemical reactions. It is shown that the chemical process cannot provide the particle heating for this regime, and it results from particle heating by an external field of gas discharge

    Experimental and numerical studies of nonequilibrium effects in framework of magnetohydrodynamic parachute concept

    No full text
    The magnetohydrodynamic (MHD) parachute effect is studied numerically for the reentry conditions. The effects of the extra ionization due to induced electric field U Ă— B are taken into account. The efficiency of MHD interaction in terms of drag is estimated. For the flight conditions under consideration, the increase of total drag due to electromagnetic one is more than twice
