Abstract :
This present work is a continuation and
validation of the results explained in a previous paper
titled A Rigorous Experimental Technique for Measuring
the Thermal Diffusivity of Metals and goes further to
describe the notion of dimensionless time tD practical for
solving the energy-density field distribution in 4D space.
Moreover, the notion of dimensionless time and statistical
characteristic length of the 3D material object is
introduced, defined and proved effective.
We have carried out a preliminary experimental
investigation and a theoretical analysis on five 3D
geometric objects of different shapes in aluminum and
steel and the results obtained for the thermal diffusivity
are in good agreement with the thermal tables
