Abstract
In this study heat conduction problems are examined to ascertain the range of applications where hyperbolic non-Fourier effects are significant and the traditional Fourier heat conduction equation leads to inaccurate temperature and heat flux profiles. It is shown that the parameters of importance are the ratio of the thermal length scale (mean free path) to the characteristic physical length scale and the ratio of thermal relaxation time to the physical time scale of the imposed thermal conditions.
