Abstract
A theoretical model has been developed to evaluate the temperature and velocity of a spherical particle at any instant during its flight in a plasma flame. Computations, which have been made for an alumina particle in this part (Part I) of the study, showed that neglecting temperature gradient in liquid film or solid core will lead to error in calculation of particle temperature and velocity. But this error is comparatively less for larger Al 2O 3 particles (about 50 μm) than for smaller ones (below 25 μ). This has been explained in terms of the negligible extent of size reduction of the particles due to the large values of heat of vaporisation and thermal conductivity of alumina. This vaporisation aspect has also been verified experimentally.
