Abstract

Heat transfer analysis is used to model temperatures in a ceramic rod heated in a microwave resonant cavity, while stationary and while moving through the cavity at a steady speed. The calculated temperatures were compared to measured temperatures from carefully controlled experiments using a traveling wave tube microwave source. The model results assuming uniform electromagnetic fields help to explain some features of the experiments thought to be attributable to nonuniform field patterns in the applicator. This work is the first step in the development of applicator designs and heating control strategies for continuous processing of thermal runaway materials, such as metal oxide ceramic fibers.
