Description
Summary:— Metallothermic SHS in conditions of artificial gravity was numerically modelled for the 3NiO + 2Al → Al 2 O 3 + 3Ni reaction taken as an example. The process was assumed to include (a) high-temperature combustion reaction yielding liquid products, (b) their gravity-assisted separation, and (c) cooling down. In our ‘throughout’ mathematical model, a three-component emulsion—gas, metal, and ceramics—with individual translational velocities and temperatures was considered. Our model may expectedly extend the range of control means for SHS reactions in extreme conditions.
