The present model deals with the consequence of Dufour, activation energy, and generation of heat on electromagnetohydrodynamic flow of hyperbolic tangent nanofluid via a stretching sheet. This offers a broad significance in several engineering fields. With adequate similarity variables, the regulating governing equations of PDEs are renovated into nonlinear ODEs. The numerical output of the produced ordinary differential equations is conducted with MATLAB bvp4c. The influence of increasing features on temperature, velocity, concentration patterns, drag force coefficient, Sherwood number and Nusselt number is depicted graphically and numerically. Hence, the resultant conclusions are confirmed utilising contrast with earlier output. Interestingly, the activation energy retards the nanofluid's tangential hyperbolic concentration distribution and the rise in temperature of the hyperbolic tangential nanofluid flow is traceable to an increase in the Dufour effect, However, the electromagnetohydrodynamic variable increases the velocity distribution, which influences the Power law index. Conclusively, the rate of heat transfer is inhibited when the thermophoresis parameter, heat source and the Weissenberg number are enhanced.
本模型研究了杜福尔效应、活化能和热生成对通过拉伸片的双曲正切纳米流体的电磁流体动力学流动的影响。这在多个工程领域具有广泛的意义。通过适当的相似变量,将偏微分方程的控制方程转化为非线性常微分方程。利用MATLAB bvp4c对所产生的常微分方程进行数值求解。以图形和数值方式描述了增加的特征对温度、速度、浓度分布、阻力系数、舍伍德数和努塞尔数的影响。因此,通过与早期结果对比来确认所得结论。有趣的是,活化能阻碍了纳米流体的切向双曲浓度分布,双曲正切纳米流体流动温度的升高可归因于杜福尔效应的增加,然而,电磁流体动力学变量增加了速度分布,这影响了幂律指数。最后,当热泳参数、热源和魏森伯格数增加时,热传递速率受到抑制。
