Abstract
To investigate the heat transfer phenomena in a flat cylindrical model food by microwave heating, temperature distributions were calculated numerically by fundamental equations under certain assumption by a mat hematical model considered the angle oi microwave incidence. The tempe rature distributions changed with their radius and as the radius becam e larger the region of hot-spots moved from a center to surroundings o i the cylinder. To check these calculated results, observation of the temperature distributions in the cylindrical modeling samples by a syn thetic paste and measurement oi the temperature by thermocouples were performed under the same operating conditions as those of the theoreti cal analysis. The calculated temperature distributions agreed closely with the measured and observed ones.
