由于纳米颗粒在太阳能系统和热工程中的捕获应用，纳米技术领域的关键发展引起了许多学者对纳米颗粒相互作用的关注。更大的能量消耗对热科学提出了挑战，因此热工程试图通过增加流体的导热系数来解决这个问题。通过在基液中掺入纳米颗粒，可以提高常规流体的导热率。考虑到这一点，本研究项目致力于在延伸片材上磁流体动力水基混合流体的稳定三维旋转流中利用纳米颗粒。氧化铝 (Al2O3) 和银 (Ag) 纳米颗粒与水 (H2O) 一起用作基液。在倾斜磁场的影响下捕获纳米粒子的速度，并通过热辐射检查热量的传输。物理模型生成偏微分方程，然后转换为一组等效的非线性常微分方程。数值计算的目的是通过Lobatto IIIA方法进行的，该方法是Matlab方案bvp4c的一种并且基于有限差分法。在存在和不存在磁场的情况下用不同的参数解释了速度分布的几何形状，并在倾斜和垂直磁场的影响下解释了混合纳米流体的能量。 f 和 g 曲线的偏导数逐渐增加，因为磁场增强导致速度降低。 Al2O3 和 Ag 纳米颗粒浓度的增加会产生更大的速度。旋转参数表示纳米粒子的旋转；由于这些旋转，速度的线性分量和角分量在存在和不存在磁效应的情况下都会增加。
Key developments in the field of nanotechnology have drawn the attention of many scholars toward the interaction of nanoparticles due to their capturing applications in solar energy systems and thermal engineering. Larger consumption of energy posed a challenge for thermal science, so thermal engineering is trying to solve this issue by increasing the thermal conductivity of the fluid. The thermal conductivity of conventional fluid is increased by incorporating the nanoparticles in the base fluid. Keeping this in mind, the present research project addresses the utilization of nanoparticles in a steady three-dimensional rotating flow of magnetohydrodynamic water-based hybrid fluid over an extending sheet. Nanoparticles of aluminum oxide (Al2O3) and silver (Ag) are being used with water (H2O) as base fluid. The velocity of nanoparticles is being captured under the influence of an inclined magnetic field and the transport of heat is scrutinized through thermal radiation. The physical model generates partial differential equations and then transported into an equivalent set of a nonlinear ordinary differential equations. The purpose of numerical computation is made by the Lobatto IIIA method, which is a type of Matlab scheme bvp4c and based on the finite difference method. Geometry of velocity profile is explained with different parameters in presence and absence of magnetic field and energy of hybrid nanofluid is explained under the influence of the inclined and perpendicular magnetic field. Gradual increment in partial derivative both f and g profiles because strengthen the magnetic field results lower velocity. An increment in nanoparticle concentration of Al2O3 and Ag gives a larger magnitude of velocity. The rotation parameter shows the rotation of nanoparticles; due to these rotations both linear and angular components of velocity increase in the presence and absence of a magnetic effect.
