Characteristics of heat and mass transfer to the wall of a confined-jet plasma flow reactor in the processes of nanopowder preparation from metals and their compounds

Abstract

The characteristics of heat and mass transfer to the wall of a confined-jet plasma flow reactor on the basis of an electric arc plasmatron in the processes of nanopowder preparation from metals and their compounds are studied experimentally. Nanopowders are prepared from copper, tungsten, aluminum oxide, and a composition based on tungsten carbides. The heat flow distribution and the distribution of the mass flow of nanoparticles to the reactor surface at different parameters of the nanopowder preparation processes are studied.
