这项研究已管理的调查熵产生的倾斜磁场（MG）的Jeffery纳米流体流的拉伸表面上含有粘性耗散。在磁流体磁流问题中同样考虑了热的产生或吸收效应，而电场被认为是可以忽略的。边界层的方法被纳入简化的建议的控制方程，其中分析的目标是集中在表面附近的流体问题。无量纲参数的概念被用来简化所提出的系统，克服了问题的复杂性。松弛和延迟时间也被认为是非牛顿Jeffrey流体模型的倾斜MG上的Jeffery纳米流体流的熵产生更好的分析拉伸表面上包含粘性耗散。强度的分析同伦分析方法被用来寻找解决方案的建议的流体系统的能量，动量和浓度，这是有效的在空间域。流动参数的图形解释已被纳入。本文沿着数值解，对本文计算的解析解（HAM）的收敛性进行了分析，并对薄板表面速度梯度f "“（0）进行了比较。第二定律分析的目的可以通过增加有限差分温度参数的大小来实现。作为研究的一个特例，本文还对牛顿流体的研究进行了描述。还为牛顿和非牛顿流体模型提供流线图案。
This study has been managed for the investigation of entropy generation of inclined magnetic field (MG) on the Jeffery nanofluid flow on a stretching surface containing viscous dissipation. Heat generation or absorption effects are likewise considered on the magnetohydromagnetic flow problem and electric field is considered negligible. The boundary layer approach is incorporated for simplification of the proposed governing equations in which the target of analysis is focused near the surface of the fluidic problem. The concept of dimension-less parameters are used for simplification of the proposed system which overcomes the complexity of the problem. The relaxation and retardation times are also considered for the non-Newtonian Jeffrey fluid model for better analysis of the entropy generation of inclined MG on the Jeffery nanofluid flow on a stretching surface containing viscous dissipation. The strength of analytical homotopy analysis approach is employed for finding the solutions of the proposed fluidic system in terms of energy, momentum and concentration which is effective in the spatial domain. Graphical explanation for flow parameters have been incorporated. The tabular description is given for the convergence analysis and comparison of velocity gradient at the sheet surface f '' (0) for analytical solution (HAM) computed in this manuscript along with the numerical solution. The aim of second law analysis can be achieved by increasing the magnitude of the finite different temperature parameter. The current study is also described for Newtonian fluid as a special case of our study. Stream lines patterns are also provided for both Newtonian and non-Newtonian fluid models.
