摘要

非线性时间分数扩散方程(NTFDEs)被广泛应用于火山喷发、扩散过程、地震、脑肿瘤和水中土壤动力学等各种自然过程的建模。解决这些问题相当具有挑战性。因此,设计有效的数值方法是一个活跃的研究领域。所使用的分数阶导数是卡普托类型。本文将Formable变换与Adomian分解(ADM)相结合,提出了一种基于混合级数的处理NTFDEs的方法。研究了该方法的稳定性和收敛性。通过算例验证了该方法的有效性。数值计算结果表明,所提出的方法是求解NTFDEs的有效方法,且计算结果准确。

Formable transform Adomian decomposition method for solving nonlinear time-fractional diffusion equation
Nonlinear time-fractional diffusion equations (NTFDEs) are widely applied for modeling various natural processes like volcanic eruption, diffusion processes, earthquakes, brain tumors, and the dynamics of soil in water. Solving these problems is quite challenging. So, designing effective numerical approaches is an active research area. The fractional derivative used is the Caputo type. In this paper, we develop the hybrid series based method by combining the Formable transform and Adomian decomposition method (ADM) for treating the NTFDEs. The stability and convergence of the developed series based method have been investigated. The effectiveness of the introduced method is investigated by solving two test examples. The obtained numerical results show that the proposed method is efficient for solving NTFDEs and gives accurate results.
