Аннотация

A mathematical model for axisymmetric turbulent two phase particle laden plasma flow has been used for numerical analysis of interphase momentum heat and mass transfer during evaporation of Si particles injected in a DC nitrogen plasma flow. Calculated plasma temperature field in the reactor, particle traces and some parameters (plasma and particle temperature, particle Re and Nu numbers, ratio of radiative to conductive and convective heat transferred to the particles and instantaneous particle diameter) along their traces are presented and discussed. Results of analysis show that there are numerous critical parameters affecting evaporation which must be considered and/or carefully optimized in order to obtain a highly efficient process.
