| Abstract | Specific heat, thermal conductivity and thermal diffusivity of cassava roots and chips were determined experimentally. Specific heat determination by the method of mixtures was found to be
satisfactory for cassava roots. Specific heat values were found to be dependent on both the temperature and moisture content of the sample. Effect of
moisture was more predominant and linear relationships were observed between specific heat and moisture content. A generalized equation was also developed using temperature and moisture content terms .
Transient line heat source technique was employed to determine the thermal conductivity. Both the chips and solid samples showed a linear in
crease in the thermal conductivity values with moisture content and as well
as the temperatures.
Thermal diffusivity was determined by three methods, the transient heat source techniques, method suggest by BAIRD and GAFFNEY (1976) and transient cooling using Fourier l aw. Line heat source technique was not found suitable for larger chip size while with the solid samples it appeared to be satisfactory. Baird and Gaffney suggested method was also found to be suitable and satisfactory for solid samples. Diffusivity values obtained by these two later methods were in close comparison with each other |
