This brief investigates analytically non-Fourier effects in high flux conditions using the relaxation model for heat conduction. Unlike the Fourier model, the relaxation model predicts an instantaneous jump in the surface temperature of solids subjected to a step change in the surface heat flux. Under sufficiently high flux, 107 w/cm2, this jump in temperature may be several hundred degrees in magnitude, resulting in severe thermal stresses at the surface.
