The time‐dependent slip flow and heat transport of the Cu‐Al₂O₃ hybrid nanofluid through a vertical permeable plate with Hall current and variable suction is investigated. An exponential heat source and quadratic convection effects are considered. The dimensionless governing equations are solved analytically using the regular perturbation method. The graph of variation of the different flow fields with respect to the distance from the plate is drawn for the analysis. It is established that the exponential heat source aspect increased the temperature profile while the quadratic convection aspect decreased the temperature profile. The applied magnetic field and nonlinear convection aspects reduce the axial velocity field. The quadratic convection and exponential space‐dependent heat source phenomena are favorable to friction factors. Furthermore, the global heat transfer is increased in the presence of an exponential space dependent heat source and hybrid nanoparticles.

具有霍尔电流，可变吸力和指数热源的Cu-Al2O3杂化纳米液体的二次对流输运

Cu‐Al ₂ O ₃随时间变化的滑流和传热通过具有霍尔电流和可变吸力的垂直渗透板研究了混合纳米流体。考虑了指数热源和二次对流效应。无量纲控制方程使用常规摄动法进行解析求解。绘制了不同流场相对于距板的距离的变化曲线图，以进行分析。已经确定，指数热源方面增加了温度分布，而二次对流方面减少了温度分布。施加的磁场和非线性对流方面会减小轴向速度场。二次对流和指数依赖空间的热源现象有利于摩擦系数。此外，
