Nanofluids are the diluted interruptions of nano-sized particles in base fluid such as oil, ethylene glycol, water etc. Nanofluids have wide applications in industries because of their enhanced thermal properties. In present article, the stability analysis of MHD (Magneto-hydro-dynamic) Poiseuille flow of thermocapillary liquid layers of shear thinning nanofluids with oxide nanoparticles in base fluid (water) by imposing transverse magnetic field are studied. The oxide nanoparticles of Aluminum oxide (Al₂O₃), copper oxide (CuO), graphene oxide (GO), Iron oxide (Fe₃O₄), and titanium oxide (TiO₂) are used. Numerical method used in current work is “cheybeshev collocation method”. To finding the eigenvalues from generalized Orr-sommerfeld equations, an algorithm named “QZ (Qualitat and Zuverlassigkeit)” used. The stability of different oxide nanoparticles based water nanofluids are compared and discussed through graphs. It has been found that Iron oxide based water nanofluid flow has more destabilizing effect and graphene oxide based water nanofluid flow has more stabilizing effect as compared to other oxide nanoparticles.

纳米流体是基础流体（如油，乙二醇，水等）中纳米尺寸颗粒的稀释稀释物。纳米流体由于其增强的热性能而在工业中得到了广泛的应用。在本文中，通过施加横向磁场，对剪切稀化纳米流体与氧化物纳米颗粒在基液（水中）中的热稀疏液的热毛细管液层的MHD（磁流体动力学）泊流进行了稳定性分析。氧化铝（Al ₂ O ₃），氧化铜（CuO），氧化石墨烯（GO），氧化铁（Fe ₃ O ₄）和氧化钛（TiO ₂）的氧化物纳米颗粒。）。当前工作中使用的数值方法是“ cheybeshev配置方法”。为了从广义的Orr-sommerfeld方程中找到特征值，使用了一种名为“ QZ（Qualitat and Zuverlassigkeit）”的算法。通过图表比较和讨论了基于氧化物纳米颗粒的水纳米流体的稳定性。已经发现，与其他氧化物纳米颗粒相比，基于氧化铁的水纳米流体流具有更多的去稳定化作用，而基于氧化石墨烯的水纳米流体流具有更稳定的作用。
