ABSTRACT:
The classical heat conduction equation is derived from the assumption that
the temperature increases immediately after heat transfer, but the increase of
temperature is a slow process, so the memory-dependent heat conduction
model has been reconstructed. Numerical results show that the solution of
the initial boundary value problem of the new model is similar to that of the
classical heat conduction equation, but its propagation speed is slower than
that of the latter. In addition, the propagation speed of the former is also affected
by time delay and kernel function.
