- Abstract
Thermal conductivity values for heat-treated wild cherry (Cerasus avium (L.) Monench) were measured for radial and tangential directions and compared with those for untreated cherry wood. The wild cherry was heat-treated at a temperature of 212°C for two periods of time: 1.5-2.5 hours, respectively. The thermal conductivity test was performed with a quick thermal conductivity meter based on the ASTM C1113-99 (2004) hot-wire method, and measurements were carried out at the room temperature of 20°C. The results show that the heat treatment caused an important decrease on thermal conductivity of wood compared to untreated wood and the thermal conductivity decreased with increasing heat treatment duration. The highest decrease in thermal conductivity was recorded for a treatment duration of 2.5h. Compared with untreated cherry wood, the thermal conductivity on tangential direction, and radial direction of 1.5h and 2.5h heat-treated cherry wood decreased with 22.21%, 19.76% and 29.43%, 29.67% respectively. Radial thermal conductivity was similar to the tangential thermal conductivity. The data are useful when calculating the energy required to kiln-dry lumber and predicting the thermal insulating qualities of log homes made from the species.
