ABSTRACT

ABSTRACT: The importance of wood from viewpoint of sustainable development is mentioned, because it is a sustainable resource against the limited mineral resources and it is a stock of fixed carbon from carbon dioxide by photosynthesis against the global warming. The engineering evaluation of its good points can encourage the more effective use of wood as substitute of mineral resources and give us the sustainable forestry. In this paper, good tactile warmth of wood is treated as one of its good points. The relationship between the contact surface temperature and the thermal effusivity is derived from the theoretical analysis of heat transfer phenomenon, which explains the some experimental knowledge on tactile warmth of wood and other materials rationally and quantitatively. Finally, the contact surface temperature and the thermal effusivity are proposed as engineering measures to evaluate the tactile warmth of wood and other materials.
