...) theory, in which Fourier's law was modified by using ( τ q , τ T ) two-time delay constants. The delay time τ q is the heat flux phase lag caused by fast transient effects of thermal inertia and τ T is the temperature gradient phase lag due to microstructural...

... approach. The numerical inversion method is employed for the inversion of Laplace and Fourier transforms. Findings The solutions are presented graphically for different values of time delay and kernel function. Originality/value The governing coupled equations of the new generalized...
