一类推广Blasius问题的非迭代变换法

A Non-Iterative Transformation Method for an Extended Blasius Problem

Riccardo Fazio

摘要:

在本文中,我们定义了一个非迭代转换方法的扩展Blasius问题。最初的非迭代变换方法是基于标度不变性的性质,由Töpfer在1912年为经典的Blasius问题定义的。这种方法允许我们通过求解一个相关的初值问题,然后对得到的数值解进行重新标度,来数值求解一个边值问题。近年来,我们已经看到了非迭代变换方法的几个感兴趣的问题的应用。通过网格加密策略和Richardson外推技术,得到的数值结果得到了改善。被发现是在良好的协议与文献中提供的。

英文摘要:

In this paper we define a non-iterative transformation method for an Extended Blasius Problem. The original non-iterative transformation method, which is based on scaling invariance properties, was defined for the classical Blasius problem by Töpfer in 1912. This method allows us to solve numerically a boundary value problem by solving a related initial value problem and then rescaling the obtained numerical solution. In recent years, we have seen applications of the non-iterative transformation method to several problems of interest. The obtained numerical results, are improved by both a mesh refinement strategy and the Richardson's extrapolation technique.%, are found to be in good agreement with those available in literature.
