摘要

本研究的目的是研究纳米流体在粘性和欧姆耗散的影响下通过拉伸片的稳定不可压缩二维流体磁边界层流动。目前的问题是借助一种叫做DTM-Pade近似的分析技术得到的。流动的数学模型以偏微分方程的形式考虑,并通过适当的相似变换将其转化为微分方程。热泳数Nt、布朗运动数Nb、普朗特数Pr、路易斯数Le、磁场M、吸力/注入S、Eckart数Ec等固定参数的作用力用图表示。结果表明,磁性参数M、吸力参数S和非线性拉伸参数n对速度分布的影响更大,而当普朗特数增加时,对温度分布的影响则相反。刘易斯数和其他参数在浓度分布中表现出增加的行为。

MHD Nanofluid boundary layer flow over a stretching sheet with viscous, ohmic dissipation
The objective of this research is to examine the steady incompressible two-dimensional hydromagnetic boundary layer flow of nanofluid passing through a stretched sheet in the influence of viscous and ohmic dissipations. The present problem is obtained with the help of an analytical technique called DTM-Pade Approximation. The mathematical modeling of the flow is considered in the form of the partial differential equation and is transformed into a differential equation through suitable similarity transformation. The force of fixed parameters like thermophoresis number Nt, Brownian motion number Nb, Prandtl number Pr, Lewis number Le, Magnetic field M, suction/injection S and Eckart number Ec are displayed with the aid of Figures. Our outcomes showed a greater trend in the velocity profile for the parameters of magnetics M, suction S, and nonlinear stretching parameter n. While the reverse trend is found against the temperature profile when the Prandtl number increases. Lewis number and other parameters have shown increasing behavior in the concentration profile.
