In this attempt, we scrutinize the effects of Sutterby nanoliquid flow deformed by a linearly stretchable sheet. Inclined magnetic field is included to explore the features of electrically conducting fluid. Thermal stratification phenomenon is implemented over a horizontal sheet to elaborate the features of heat transfer. Variable fluid feature is also accounted. Zero mass flux condition is incorporated along with Brownian diffusion and thermophoresis phenomenon Using the suitable transformations, the system of partial differential equations are transmuted into coupled system of ordinary differential equations. Approximate analytical solutions are computed via homotopic approach. Graphical behavior of applicable parameters on temperature, velocity, and concentration fields are illustrated and elaborated. Skin friction coefficient and Nusselt number are computed and analyzed. It is found that increase in fluid parameter declines the velocity field whereas temperature field rises for higher thermal conductivity parameter. Heat transfer rate decays for thermal stratification phenomenon. The current attempt is incorporated in diverse processes of industry and engineering including cooling and heating processes in solar water heater, building insulation, electronics, turbines, transportation, power generation, geothermal systems, and engines. Moreover, Sutterby model predicts the characteristics of pseudo-plastic and dilatant fluids. This model is very useful for high polymer solutions and polymer melts which are important industrial materials. Owing by such applications, the present examination has been established.

零质量通量条件下Sutterby纳米流体的热分层流分析

在此尝试中,我们仔细研究了可线性拉伸片变形的Sutterby纳米液体流的影响。包括倾斜磁场以探索导电流体的特征。在水平板上实施热分层现象以详细说明传热的特征。可变流体特征也被考虑。将零质量通量条件与布朗扩散和热泳现象结合在一起,使用适当的变换,将偏微分方程组转化为常微分方程的耦合系统。近似分析解是通过同位论方法计算的。说明并阐述了适用参数在温度,速度和浓度场上的图形行为。计算并分析了皮肤摩擦系数和努塞尔数。可以发现,流体参数的增加会降低速度场,而温度场会随着较高的热导率参数而上升。传热速率因热分层现象而下降。当前的尝试被并入了各种工业和工程过程,包括太阳能热水器,建筑物隔热,电子,涡轮机,运输,发电,地热系统和发动机中的冷却和加热过程。此外,Sutterby模型可预测假塑性流体和膨胀流体的特征。该模型对于作为重要工业材料的高聚物溶液和聚合物熔体非常有用。由于这种应用,目前的检查已经建立。可以发现,流体参数的增加会降低速度场,而温度场会随着较高的热导率参数而上升。传热速率因热分层现象而下降。当前的尝试被并入了各种工业和工程过程,包括太阳能热水器,建筑物隔热,电子,涡轮机,运输,发电,地热系统和发动机中的冷却和加热过程。此外,Sutterby模型可预测假塑性流体和膨胀流体的特征。该模型对于作为重要工业材料的高聚物溶液和聚合物熔体非常有用。由于这种应用,目前的检查已经建立。可以发现,流体参数的增加会降低速度场,而温度场会随着较高的热导率参数而上升。传热速率因热分层现象而下降。当前的尝试被并入了各种工业和工程过程,包括太阳能热水器,建筑保温,电子,涡轮机,运输,发电,地热系统和发动机中的冷却和加热过程。此外,Sutterby模型可预测假塑性流体和膨胀流体的特征。该模型对于作为重要工业材料的高聚物溶液和聚合物熔体非常有用。由于这种应用,目前的检查已经建立。
