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.
