The Model Research of Wood Thermal Diffusivity
Zhong Yun, NW Sci · Xibei Linxueyuan xuebao · 2003
The relationship between thermal diffusivity and temperature, moisture content, density and velocity of sound is studied. The experiment regression equations on the thermal diffusivity in the choral and redial direction were deduced. By comparing with the practical value, the average relative error of the theoretical values less than 0.3%, and average absolute value of relative error is less than 4.8%.
