摘要

本研究的目的是将偏微分方程在时间坐标上的两种物理效应联系起来,特别是多重延迟时间和分数阶导数。时间分数阶延迟偏微分方程(TFDPDEs)通常用来解释一些复杂的物理现象。本文利用微扰迭代算法(PIA)中的Caputo意义的分数阶导数,对具有x收缩和t比例延迟的TFDPDE进行了数值求解。用PIA求解了几个著名的数值例子,并与精确解进行了比较。此外,用图形形式描述了®的不同值,以显示它们的分数行为。延迟项k在本TFDPDE研究中也得到了广泛的讨论。数值结果表明,该方法可靠、方便,对现代计算应用具有吸引力。

Numerical Solution of Time Fractional Delay Partial Differential Equations by Perturbation Iteration Algorithm
The aim of this research was to relate two physical effects for partial differential equations on the time-coordinate, notably the multipledelay times and fractional-derivative. Time Fractional Delay Partial Differential Equations (TFDPDEs) usually interpret some complex physical phenomenon. This study works to solve TFDPDE with shrinking in x and proportional delays in t numerically by utilizing the fractional derivative of Caputo sense in the numerical method known as Perturbation Iteration Algorithm (PIA). A few famous numerical examples have been solved using PIA and their comparison with an exact solutions is illustrated for ® = 1. Also, different values of ® have been depicted in graphical form to show their fractional behavior. The delay term k is also discussed extensively in this TFDPDE study. Numerical results show that this technique is reliable, convenient, and attractive for computational use in modern times.
