The current study examines the numerical simulation of the nanoliquid boundary layer flow comprising gyrotactic microbes with mass and energy transmission across a stretching inclined cylinder. The consequences of chemical reaction, heat generation/absorption, buoyancy force and Arrhenius activation energy is also considered on the nanofluid flow. The flow mechanism has been modeled in the form of system of nonlinear partial differential equations (PDEs). That system of PDEs is further transform into the dimensionless set of ordinary differential equations (ODEs) through the similarity substitutions. The obtained set of differential equations are numerically computed through the parametric continuation method (PCM). The effects of the distinct physical constraints on the energy, velocity, mass and the motile microbe profiles are discoursed and evaluated through Tables and Figures. It has been noticed that the velocity curve drops with the influence of inclination angle and Richardson number, while enhances against the variation of curvature factor. Furthermore, the energy field boosts with the upshot of inclination angle and heat source term, while declines with the influence of Prandtl number and Richardson number.
本研究考察了包含热泳微生物的纳米液边界层流动的数值模拟,该流动涉及质量和能量通过拉伸倾斜圆柱的传输。化学反应、热生成/吸收、浮力和 Arrhenius 激活能对纳米流体流动也有影响。流动机制被建模为非线性偏微分方程组(PDEs)的形式。该 PDE 系统通过相似性替代进一步转换为无量纲常微分方程组(ODEs)。通过参数连续法(PCM)对得到的微分方程组进行数值计算。通过表格和图形讨论和评估了不同物理约束对能量、速度、质量和游动微生物分布的影响。已经注意到,速度曲线随着倾斜角和理查森数的影响而下降,而随着曲率因子的变化而增加。此外,能量场随着倾斜角和热源项的增加而增加,而随着普朗特数和理查森数的影响而减少。
