Cover Story: A Riemann–Liouville distributed-order space fractional operator was introduced to model diffusion phenomena, exhibiting multi-scale varying characteristics. The proposed two-dimensional fractional diffusion model was solved by an alternating direction implicit scheme. Following this, we proved the stability and convergence of the numerical method. An extrapolated technique was implemented to improve the convergence order of the implicit method. Furthermore, a fast Bi-CGSTAB algorithm was developed to reduce computational costs. Finally, two numerical examples were provided to verify the effectiveness of the proposed numerical methods. This research may offer more insights into the application of fractional calculus and numerical techniques for solving fractional systems. View this paper
