Abstract
In this study, the heat and mass transfer characteristics of a two-dimensional incompressible Oldroyd-B fluid over a stretching sheet in the presence of Soret, Dufour, and nanoparticles are investigated. The effects of elasticity and magnetohydrodynamics on flow are being studied. The transport equations contain Brownian motion and thermophoresis. The governing partial differential equations and associated boundary conditions are dimension less using sufficient similarity variables. The resulting ordinary differential equations are solved using the successive linearization method. It has been quantitatively measured and explored how different embedded thermophysical characteristics affect fluid velocity, temperature, concentration, Nusselt number, and Sherwood number. The temperature and concentration distribution increase when the values of Du and Sr rise. As Nb estimations rise, Nusselt number estimates fall. It should be emphasized that the influence is shown to be quite modest as a retardation time is increased. A comparison of one instance of our findings with those previously published in the literature reveals a very strong agreement.
本研究探讨了二维不可压缩奥尔德罗伊德-B 流体在存在索雷特、杜福尔和纳米颗粒的情况下在拉伸片上的传热和传质特性。还研究了弹性和磁流体力学对流动的影响。传输方程包含布朗运动和热泳。利用充分的相似性变量,对支配偏微分方程和相关的边界条件进行减维。由此产生的常微分方程采用连续线性化方法求解。对不同的嵌入式热物理特性如何影响流体速度、温度、浓度、努塞尔特数和舍伍德数进行了定量测量和探索。当 Du 和 Sr 值升高时,温度和浓度分布也随之增加。随着 Nb 估计值的上升,努塞尔特数估计值也会下降。需要强调的是,随着延迟时间的增加,这种影响并不明显。将我们的一个研究结果与以前发表的文献进行比较,发现两者非常一致。
