Influence of Density and Water Content on The Thermal Diffusivity of Wood Chips

The use of agro-industrial residues are currently experiencing an undeniable revival interest in developing fully renewable insulation materials, that can be competitive price and performance, addition low embodied energy. Among these vegetable waste materials; wood chips. These latter light, compressible very sensitive to water, due their highly porous structure, which constantly modifies thermal properties. main objective this study is examine the influence moisture content density on diffusivity chips, using flash method. Four theoretical models were used identify diffusivity. results obtained show a decrease with increase chips density. Furthermore, has experimental fluctuations slight maximum corresponding value W m .
