Numerical technique shows unconditionally stable behavior in nonlinear thermal wave diffusion, indicating effectiveness in analyzing rigid conductors.
This paper presents a numerical technique based on finite difference method to study numerically the behavior of a rigid thermal conductor's time-nonlinear couple system of heat wave propagation model of fractional order, where the fractional derivative is treated in the sense of Atangana-Baleanu-Caputo. It has been demonstrated via Fourier analysis that suggested scheme is unconditionally stable. Numerical experiments have been demonstrated to embed and verify the theoretical outcomes provided in this study and guarantee the effectiveness of the numerical method.
