The Numerical Analysis of Non-polar Solvent Heated by Microwave Indirectly

Abstract

When the dielectric properties of the sample are too poor to allow efficient heating by microwave radiation, the use of container that have large loss tangent values can significantly overcome these problems and enable adequate heating of the whole sample. In this paper, carbon tetrachloride at silicon carbide container with three different configurations were heated indirectly by microwave. The uniformities of temperature were analyzed using COMSOL Multiphysics under different configurations during microwave heating. It was concluded that the temperature uniformities were influenced by the parameters of different configurations, when the improvement in electric field uniformity is not obvious for one configuration, it can be significantly improved by changing to another specific configuration.
