The present work explored the heat transfer and boundary layer flow of a hybrid nanofluid past an inclined stretching/shrinking sheet with suction and buoyancy force effects. Silver (Ag) and magnesium oxide (MgO) are considered as the hybrid nanoparticles and suspended in water to form Ag-MgO/water hybrid nanofluid. The partial differential equations (PDEs) are converted into a system of ordinary differential equations (ODEs) by employing appropriate similarity transformation. The simplified mathematical model is then solved numerically using the bvp4c solver in the MATLAB software. The effects of governing parameters, namely the inclination angle, suction, stretching/shrinking, buoyancy or mixed convection and nanoparticle volume fraction parameters on the velocity and temperature profiles as well as skin friction coefficient and local Nusselt number are examined and presented graphically. The results are proven to have two solutions for both stretching and shrinking case, which consequently lead to the implementation of a stability analysis, hence confirming that only the first solution is stable. In addition, the local Nusselt number increases when the angle of inclination and suction parameters increase. The results also reveal that increasing values of Ag nanoparticle volume fraction in MgO/water nanofluid declines the local Nusselt number.

本工作探索了混合纳米流体通过倾斜的拉伸/收缩片材的传热和边界层流动，该片具有吸力和浮力作用。银（Ag）和氧化镁（MgO）被视为杂化纳米颗粒，并悬浮在水中以形成Ag-MgO /水杂化纳米流体。通过采用适当的相似度转换，将偏微分方程（PDE）转换为常微分方程（ODE）的系统。然后，使用MATLAB软件中的bvp4c求解器对简化的数学模型进行数值求解。控制参数的影响，即倾斜角度，吸力，拉伸/收缩，检查并以图形方式显示了速度或温度曲线上的浮力或混合对流和纳米粒子体积分数参数，以及皮肤摩擦系数和局部Nusselt数。事实证明，该结果对于拉伸和收缩情况都有两种解决方案，因此可以进行稳定性分析，从而确认只有第一种解决方案是稳定的。另外，当倾角和吸力参数增加时，局部努塞尔数增加。结果还表明，MgO /水纳米流体中Ag纳米颗粒体积分数的增加值会降低局部Nusselt数。结果导致进行稳定性分析，从而确认只有第一个解决方案是稳定的。另外，当倾角和吸力参数增加时，局部努塞尔数增加。结果还表明，MgO /水纳米流体中Ag纳米颗粒体积分数的增加值会降低局部Nusselt数。结果导致进行稳定性分析，从而确认只有第一个解决方案是稳定的。另外，当倾角和吸力参数增加时，局部努塞尔数增加。结果还表明，MgO /水纳米流体中Ag纳米颗粒体积分数的增加值会降低局部Nusselt数。
