Abstract

This scientific report investigates the heat transfer analysis in mixed convection flow of Maxwell fluid over an oscillating vertical plate with constant wall temperature. The problem is modelled in terms of coupled partial differential equations with initial and boundary conditions. Some suitable non-dimensional variables are introduced in order to transform the governing problem into dimensionless form. The resulting problem is solved via Laplace transform method and exact solutions for velocity, shear stress and temperature are obtained. These solutions are greatly influenced with the variation of embedded parameters which include the Prandtl number and Grashof number for various times. In the absence of free convection, the corresponding solutions representing the mechanical part of velocity reduced to the well known solutions in the literature. The total velocity is presented as a sum of both cosine and sine velocities. The unsteady velocity in each case is arranged in the form of transient and post transient parts. It is found that the post transient parts are independent of time. The solutions corresponding to Newtonian fluids are recovered as a special case and comparison between Newtonian fluid and Maxwell fluid is shown graphically.

摘要

本科学报告研究了在常壁温下,麦克斯韦流体中混合对流传热分析,在垂直摆动板上的流动。该问题通过初始和边界条件的耦合偏微分方程建模。引入了一些合适的无量纲变量,以便将控制问题转化为无量纲形式。通过拉普拉斯变换方法求解得到了速度、剪切应力和温度的精确解。这些解受到嵌入参数的变化极大影响,包括普朗特数和各种时间下的格拉肖夫数。在没有自由对流的情况下,代表速度机械部分的相应解简化为文献中已知的解。总速度表示为余弦和正弦速度的和。在每种情况下,非稳态速度都以瞬态和后瞬态部分的形式排列。发现后瞬态部分与时间无关。牛顿流体的解作为特殊情况得到恢复,并以图形方式显示了牛顿流体和麦克斯韦流体之间的比较。
