摘要

通过数值研究，对流经螺旋旋转盘的旋转停滞点二级液体进行了分析。对热传递进行了分析。问题以耦合偏微分方程的形式提出，随后根据相似变量进行了简化。采用 Keller-Box (KB) 程序进行数值求解。对影响速度和温度分布的相关参数进行了介绍和解释。以数值数据的形式报告了表皮摩擦系数和努塞尔特数。通过与文献中已有资料的对比，对本结果进行了验证。本研究指出，边界厚度层随着粘弹性和旋转参数的增加而增加。旋转参数和粘弹性参数都能抵抗温度。旋转参数增加了径向皮肤摩擦和热传导率，同时减小了漩涡皮肤摩擦。

Rotational Stagnation Point Non-Newtonian Second-Grade Fluid Flowing over Spiraling Disk

Numerical study is conducted to execute the analysis of rotational stagnation point second-grade liquid flowing over the spiraling rotatory disk. Heat transmission analysis is accounted. The problem is formulated in the coupled partial differential equations forms which are later simplified in view of similar variables. The Keller-Box (KB) procedure is adopted for the execution of numerical solutions. The involved parameters influences on the velocity and temperature profiles are presented and interpreted. The skin-frictions and Nusselt number are reported in the forms of numerical data. The present results are verified through the comparison with already available material in the literature. This study addressed that the thickness layer of boundary augmented against the incrementing viscoelastic and rotational parameters. Both rotational and viscoelasticity resist the temperature. The rotational parameter rises radial skin-friction and heat transmission rate while diminishes the swirl skin friction.

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.
