Abstract:
The mechanism of heat transfer of submicron MgO particles in the combustion zone during their growth is studied at pressures of 10$^4$ – 10$^5$ Pa using opticospectral measurements and numerical simulation. It is shown that at the early stage of particle growth, heat transfer is caused exclusively by collisions with gas molecules with an energy-accommodation coefficient of $\sim$ 0.01 – 0.02. During particle growth and with decrease in pressure, the role of radiation increases, and, ultimately, radiation becomes a leading mechanism of heat transfer.
