(iii) thermal diffusivity (α). All these properties are interrelated by DO U / c p. While conductivity, den-sity and specific heat capacity are intrinsic physical rock properties, the thermal diffusivity is an artificial parameter that results from the algebraic

Determination of thermal diffusivity

This substance size is equal to the quotient of thermal conductivity and the product of specific heat capacity and density. From this formula, the unit of measure [m/s] is calculated. The thermal diffusivity is required for the assessment of heating and cooling processes, temperature changes in living spaces and thermal stresses in components.
