Abstract

ABSTRACT In this article, we explore the three-dimensional boundary-layer flow over an exponentially stretching surface in two parallel ways. Constitutive equations of a second-grade fluid are used. Instead of classical Fourier’s law, Cattaneo–Christov heat flux model is employed for the formulation of the energy equation. This model can predict the effects of thermal relaxation time on the boundary layer. The resulting partial differential equations are reduced into ordinary differential equations by similarity transformations. Homotopy Analysis Method (HAM) is employed to solve the non-linear problem. Physical impact of emerging parameters on the momentum and thermal boundary-layer thickness are studied.

指数拉伸表面上粘弹性流体三维流动的Cattaneo–Christov热通量模型

摘要在本文中，我们以两种平行的方式探讨了指数拉伸表面上的三维边界层流动。使用二级流体的本构方程。能量方程的公式采用Cattaneo–Christov热通量模型，而不是经典的傅立叶定律。该模型可以预测热弛豫时间对边界层的影响。通过相似变换将得到的偏微分方程简化为常微分方程。采用同源分析法（HAM）求解非线性问题。研究了新兴参数对动量和热边界层厚度的物理影响。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
