Two-dimensional nonlinear time fractional reaction–diffusion equation in application to sub-diffusion process of the multicomponent fluid in porous media

Abstract: In the present article, an efficient operational matrix based on the famous Laguerre polynomials is applied for the numerical solution of two-dimensional non-linear time fractional order reaction–diffusion equation. An operational matrix is constructed for fractional order differentiation and this operational matrix converts our proposed model into a system of non-linear algebraic equations through collocation which can be solved by using the Newton Iteration method. Assuming the surface layers are thermodynam… Show more

“…In order to compare the results with method [15], we listed the maximum absolute error and CPU time for γ(x, t) = 0.9 and M = 2 in Table 2. The results illustrate that the proposed method is more efficient than method [15]. Furthermore, the plots of the absolute error in the different domains are shown in Figures 1 and 2.…”

“…The effectiveness and variation of the degree of approximation r is discussed in the literature [17] . One can easily understand that the order of convergence of the numerical techniques provided in this article [17] is increases as we increase the degree of approximation and the errors in computing the numerical solution is decreases as we increase the degree of approximation. In the present article we consider the degree approximation for each numerical computation and pictorial presentation.…”
