摘要

本方案旨在为流动现象的微极流体通过膨胀/收缩表面进行,以揭示阻力系数的影响。自由对流由于浮力与辐射热能和非均匀热源/汇的结合而促进了流动特性。本研究的新颖之处在于使用了对流动特性影响很大的可变板条件。采用适当的相似变换对控制流现象进行变换,并采用龙格-库塔四阶数值处理,然后进行射击,得到变换后的非线性系统的解。此外,还通过图形和表格的形式给出了表征参数的仿真结果。主要发现是;轴向速度的提高以流体的非牛顿行为为特征,空间热源和温度热源都有利于流体温度的提高。

Characteristics of variable plate conditions on the time-dependent flow of polar fluid over an expanding/contracting surface
The present scenario intended for the flow phenomena of micropolar fluid past an expanding/contracting surface is carried out to reveal the impact of a drag coefficient. Free convection due to the inclusion of the buoyant forces along with the radiative heat energy and non-uniform heat source/sink encourages the flow properties. The novelty of the present investigation is the use of variable plate conditions that affect the flow properties greatly. The transformation of the governing flow phenomena is obtained with the use of suitable similarity transformation and numerical treatment based upon Runge-Kutta fourth-order followed by shooting is imposed to get the solution of this transformed nonlinear system. Further, the simulation of the characterizing parameters is obtained and presented via graphs and tables. The major findings are; the enhancement in the axial velocity is characterized by the non-Newtonian behavior of the fluid and both the space and temperature dependent heat source favors for the augmentation in the fluid temperature.
