Effect of melting of an inert component and melt spreading on nonstationary combustion regimes of gasless systems

The effect of the thermocapillary flow of the melting of an inert component of a gasless mixture on the spin combustion regimes of a cylindrical sample has been studied numerically. The change in the structure of the wave of spin combustion due to a change in the radius of the sample has been discussed, and new spin combustion modes has been found. Increasing the melt flow velocity leas to stabilization of the combustion – transition from spin modes to the stationary propagation of the combustion wave.
