This study briefings the roles of Coriolis, and Lorentz forces on the dynamics of rotating nanofluids flow toward a continuously stretching sheet. The nanoparticles are incorporated because of their unusual qualities like upgrade the thermal transportation, which are very important in heat exchangers, modern nanotechnology, electronics, and material sciences. The primary goal of this study is to improve heat transportation. Appropriate similarity transformations are applied for the principal PDEs to transform into nonlinear dimensionless PDEs. A widely recognized Numerical scheme known as the Finite Element Method is employed to solve the resultant convective boundary layer balances. Higher input in the solvent fraction parameter has a rising effect on the primary velocity and secondary velocity magnitude, and decreasing impact on the distributions of temperature. It is seen that growing contributions of the Coriolis, and Lorentz forces cause to moderate the primary and secondary velocities, but the temperature and concentration functions show opposite trend. The concentration, temperature, and velocities distributions for suction case is prominently than that of injection case, but inverse trend is observed for local Nusselt and Sherwood numbers. These examinations are relevant to the field of plastic films, crystal growing, paper production, heat exchanger, and bio-medicine.
本研究简述了科里奥利力和洛伦兹力对旋转纳米流体流向连续拉伸薄板的动力学的作用。纳入纳米颗粒是因为它们具有诸如提升热传输等特殊性质，这在热交换器、现代纳米技术、电子学和材料科学中非常重要。本研究的主要目标是改善热传输。对主要偏微分方程应用适当的相似变换，将其转化为非线性无量纲偏微分方程。采用一种广为人知的数值方法——有限元法来求解所得的对流边界层平衡。溶剂分数参数的较高输入对一次速度和二次速度大小有上升作用，而对温度分布有下降影响。可以看出，科里奥利力和洛伦兹力的不断增大导致一次和二次速度减缓，但温度和浓度函数呈现相反趋势。抽吸情况下的浓度、温度和速度分布比注入情况下更为显著，但局部努塞尔数和舍伍德数呈现相反趋势。这些研究与塑料薄膜、晶体生长、造纸、热交换器和生物医学领域相关。
