Abstract |
| Thermal conductivity, thermal diffusivity and thermal absorptivity of dry Elaeis Guineensis (oil palm) tree trunk have been determined at temperature range between 28 and 80°C using Bruel and Kjaer rapid thermal conductivity machine under the steady-state heat flow. Results show a mean thermal conductivity λ = (0.0613 ± 0.0009)Wm-1K-1 thermal diffusivity D = (8.96 ± 0.71) x 10-8m1s-1 and thermal absorptivity α = (20.24 ± 1.61)m-1 with a mean percentage porosity of (35.5 ± 3.1)% and specific heat capacity c = (2164.2 ± 33.6)Jkg-1K1. The low thermal conductivity, which is attributed to the high percentage of dead air space in the samples, leading to low density, makes this material a potential thermal insulator for thermal envelope, especially for building design. |
