In addition, the thermal diffusivity was also determined by a numerical computation procedure.  The specific heat of melons using the meth o d of mixtures  varied from 3.48 - 4.29 k1T/kg °C with a mean value of 3 . 926 1T ~g  °C in the temperature range of 10 to 45 °C . It was to und to be  increasing 1inearl y w:i U1 an :in crease :in the sample temperature.  Thermal conductivity values of melon based o n t h e transient  line heat source technique varied from 0 .481 to 0 . 623 W/m °C with  a n aver age value of O. 59 W/m°c in the sample temperature range of  5 t o 45 °C. A linear increase in the thermal conductivity values  with sample temperature was also observed. Techniques based o n Fourier's analysis were used in the  thermal diffusivity determination of  melons. Thermal diffusivity  was computed directly from experimentally determined specific  heat, density and thermal conductivity values. The thermal  diffusivity values determined by direct computation showed the mean  value of 1. 57 x 10- m' /s . When using Fourier' s analysis in the  heating of melon , the  mean value of thermal diffusivity was  determined to b e 1 .44 x 10- m2/s.  0aMelonsxThermal properties1 aJindal, Vinod Kumar,eChairperson1 aIllangantileke, Sarath G., eExamination Committee0 aAthapol Noomhorm,eExamination Committee2 aJICA - IPB Project, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
