Abstract
In this paper we report the thermal diffusivity of coconut shellmeasured using a laser-induced photoacoustic (PA) technique. An openPA cell in the heat transmission configuration isemployed for the investigation. Laser-induced heating of thecoconut shell is found to result in a thermoelastic bending ofthe sample. Taking into account this effect, an appropriate modification of Rosencwaig-Gersho theory for the PAeffect is made for the calculation of the thermal diffusivity. Ourinvestigation shows that coconut shell possesses a largerthermal diffusivity than ordinary wood.
