| Abstract | Specific heat, thermal conductivity and thermal diffusivity of melons were determined experimentally. 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. |
