Verification of thermal conductivity of wood materials
Kostka, Petr ; Neuberger, Pavel (advisor) ; Adamovský, Radomír (referee)
This diploma thesis deals with verifying the thermal conductivity and other thermophysical properties of different types of wood (spruce, oak, ash and maple). A special device ISOMET 2104, which is based on dynamic method of measurement, was used. Three different samples for each type of wood were used (for example, different age of trees). Values of the thermal conductivity, the thermal diffusivity and the specific heat capacity, depending on the gradually decreasing moisture of wood, were obtained. The key point of this study was finding that the values of thermophysical properties of wood materials vary significantly depending on the age, growing conditions, properties of the soil and other factors. Some of the data correspond with previously published studies but other data are in contrast to them.
