摘要

摘要在纳米流体中,本文综述了双扩散率条件下对流对磁偶应力流体非均匀通道模型(MCSFM)蠕动流动的影响。本文应用Levenberg-Marquardt过程,通过人工反向传播神经网络(LMP-ABNN)讨论了非均匀信道中的MCSF。对于二维和双向流动,建立了磁偶应力流体在纳米流体中双扩散率对流的数学表达式。通过适当的变换,将偏微分方程化为常微分方程。针对不同变化的MSCFM,基于ND求解方法生成LMP-ABNN数据集,评估了Hartmann数、热涌参数、Dufour参数、Soret参数和磁雷诺数对浓度剖面和温度剖面的影响。为了检验近似解的有效性,解释了训练和测试程序,并通过误差直方图和均方误差结果验证了性能。通过采用长波长近似和低但有限的雷诺数来简化极端非线性方程。为了描述流量的行为,显示了各种重要物理特性的图形表示。研究了哈特曼数和磁雷诺数对轴向磁场和电流密度的影响。随着热泳参数和杜福尔参数的增大,其浓度也随之增大。这是因为浓度和这两个参数有直接关系。我们观察到磁雷诺数和哈特曼数的相反行为。电流密度J z随R m的增大而增大,温度分布和溶质浓度均增大。本研究的最终结果是提供这些技术的潜力,为纳米流体和其他流体力学领域的挑战性问题提供新的见解和解决方案,并促进设计更高效和有效的微流体装置。

Intelligent computing for the double-diffusive peristaltic rheology of magneto couple stress nanomaterials
Abstract In nanofluids, the effect of convection in the presence of double diffusivity on a magneto couple stress fluid with the peristaltic flow of a model in a non-uniform channel (MCSFM) is reviewed in this article. This research discusses MCSF in a non-uniform channel by applying the Levenberg–Marquardt procedure via an artificial backpropagated neural network (LMP-ABNN). For two-dimensional and two-directional flows, mathematical formulations of double-diffusivity convection of a magneto couple stress fluid in nanofluids are developed. The partial differential equations are reduced to ordinary differential equations by using appropriate transformations. The assessment of the Hartmann number, thermophoresis parameter, Dufour parameter, Soret parameter, and magnetic Reynolds number over concentration profiles and temperature profiles is made by generating a dataset for LMP-ABNN based on the ND solve method for different variations of MSCFM. To examine the approximate solution validation, training and testing procedures are interpreted, and the performance is verified through error histogram and mean square error results. The extremely nonlinear equations are reduced by employing a long-wavelength approximation and a low but finite Reynolds number. To describe the behavior of flow quantities, graphical representations of a variety of physical characteristics of importance are shown. The impact of the Hartmann number and magnetic Reynolds number over axial magnetic field and current density is also studied. The concentration increases as the thermophoresis parameter and Dufour parameter values increase. This occurs because the concentration and both these parameters have a direct relationship. We observed opposite behavior for both the magnetic Reynolds number and the Hartman number. The behavior of current density J z increases with increasing values of R m. Both the temperature distribution and solute concentration increase. The final outcome of this study is to provide the potential for these techniques to provide new insights and solutions to challenging problems in nanofluids and other areas of fluid mechanics and to facilitate the design of more efficient and effective microfluidic devices.
