Abstract

In this paper, the mathematical model of heat and porous media equations being considered in fractional form. The Laplace residual power series method and the Laplace Adomian decomposition technique are used to compare the solutions of the fractional heat transfer and porous media equations. For this reason, a few examples are presented to understand the fractional heat transfer and porous media equations in its more accurate form. The results show the simple and sophisticated procedures of the two proposed analytical approaches, where partial differential equations are considered with fractional derivatives. The outcomes of the described methods demonstrate that they have an accurate algorithm to construct with exceptionally precise cost calculation capabilities. The obtained results are presented through tables and graphs and the approximate results are found in great contact with exact solutions.

利用分析技术比较分数传热和多孔介质方程的解法
摘要 本文考虑了分式传热和多孔介质方程的数学模型。本文采用拉普拉斯残差幂级数法和拉普拉斯阿多米分解技术来比较分式传热方程和多孔介质方程的解。为此,本文列举了几个例子,以更准确地理解分数传热方程和多孔介质方程。结果表明,在考虑带有分数导数的偏微分方程时,所提出的两种分析方法的程序既简单又复杂。所述方法的结果表明,它们具有精确的算法,可以构建异常精确的成本计算能力。所获得的结果通过表格和图表呈现,近似结果与精确解有很大的联系。
