摘要

本文研究了具有熔融效应的二级纳米材料在可拉伸弯曲表面下磁流体力学流动中的熵分析。利用热力学第一定律模拟了辐射效应下的热归因。随机运动和热泳运动的主要物理效应也被讨论。讨论了不可逆性(熵率)分析的特点。讨论了等温立方自催化在催化表面的化学反应。非线性无量纲微分系统是通过适当的变换得到的。采用最优同型分析法(OHAM)构造收敛解。讨论了物理变量对熵率、流体流动、浓度和热场的影响。曲率变量使流体流量增大,磁变量使流体流量增大。对于流体流动和热场,通过熔化变量产生相反的效果。熵分析增加了熔化变量的变化。通过热泳变量,浓度发生降低,而热场则相反。熔化变量的增加导致浓度的降低。较大的辐射变量估计值改善了熵分析。

Melting aspects in flow of second grade nanomaterial with homogeneous–heterogeneous reactions and irreversibility phenomenon: A residual error analysis
Here, we scrutinize the entropy analysis in magnetohydrodynamic flow of second-grade nanomaterials with melting effect subject to stretchable bended surface. Heat attribution is modeled through first law of thermodynamics with radiation effect. Major physical effect of random and thermophoretic motion is also addressed. Feature of irreversibility (entropy rate) analysis is also discussed. Isothermal cubic autocatalyses chemical reaction at catalytic surface is discussed. Nonlinear dimensionless differential system is developed through adequate transformation. Optimal homeotypic analysis method (OHAM) is employed to construct convergent solution. Influence of physical variables on entropy rate, fluid flow, concentration, and thermal field is discussed. An augmentation in fluid flow is noticed through curvature variable, while reverse effect holds for magnetic variable. A reverse effect holds for fluid flow and thermal field through melting variable. Entropy analysis is augmented with variation in melting variable. Reduction occurs in concentration through thermophoretic variable, while an opposite effect holds for thermal field. An increment in melting variable leads to reduced concentration. Larger estimation of radiation variable improves entropy analysis.
