چكيده فارسي :
In the present paper, compact finite difference technique is applied to solve the Rayleigh-Stokes equation in onedimensional case. The time fractional derivative is approximated by the second-order weighted and shifted Gr¨unwald difference (WSGD) formula. This study employs Crank-Nicolson and compact finite difference schemes to discretize the temporal and spatial derivatives, respectively. Finally, the efficiency of proposed method demonstrated by numerical experiment which validates the expected order of accuracy of presented method O(τ^2 + h^4).
