Abstract: | The heating process of dielectric materials by microwave with rectangular wave guide has been investigated experimentally. This experiment is operated in the TE10-dominated mode at a frequency of 2.45 GHz. It was performed for two dielectric materials, water layer and saturated porous medium. In this work, the microwave powers level, a type of dielectric materials, dimensions and positions of dielectric material on the microwave power absorb and average temperature within dielectric materials were examined in details. The results show that the locations of sample have greater effects than the other parameters. The analyses from this research serve as essential fundamentals to development of mathematic models of heat and mass transfer phenomena. |
