Abstract

The Soret and Dufour effects play a crucial role in various fields such as geosciences, groundwater pollutant migration, chemical reactor operations, binary alloy solidification, and isotope separation. This study focuses on examining the impact of mixed convective flow on hybrid nanofluid through an exponentially stretching sheet with Soret and Dufour effects. The flow is affected by factors like variable viscosity, radiation, viscous dissipation, and activation energy. Instead of the no-slip condition at the boundary, velocity slip, thermal slip, and concentration slip are considered. The physical problem is modeled using boundary layer theory, and flow patterns are expressed using partial differential equations (PDEs). These governing fluid flow equations are transformed into non-linearly coupled ordinary differential equations (ODEs) using exponential similarity transformations. These simplified ODEs are resolved using the MATLAB bvp4c package. The effects of physical parameters on velocity, temperature, and concentration are illustrated through figures. Additionally, the drag force coefficient and heat and mass transfer rates are calculated for various parameters and presented graphically and in tabular form. It is observed that compared to nanofluids, the drag force coefficient of hybrid nanofluids increases by up to 21.05% with various solute buoyancy parameters (δ). Also, the mass transfer rate of hybrid nanofluids can be increased by .96% by the chemical reaction rate (σm). A comparison of this work with previously published research has been reported.

化学反应对具有索雷特效应和杜富尔效应的指数拉伸片上混合纳米流体(GO + MoS2)流动的影响
索雷特效应和杜富尔效应在地球科学、地下水污染物迁移、化学反应器运行、二元合金凝固和同位素分离等多个领域发挥着至关重要的作用。本研究重点考察了混合对流流经具有索雷特和杜富尔效应的指数拉伸片时对混合纳米流体的影响。流动受到可变粘度、辐射、粘性耗散和活化能等因素的影响。除了边界的无滑移条件,还考虑了速度滑移、热滑移和浓度滑移。物理问题使用边界层理论建模,流动模式使用偏微分方程(PDEs)表示。通过指数相似变换,这些控制流体流动的方程被转换为非线性耦合常微分方程(ODE)。这些简化的 ODE 使用 MATLAB bvp4c 软件包进行解析。物理参数对速度、温度和浓度的影响通过数字加以说明。此外,还计算了各种参数的阻力系数以及传热和传质速率,并以图形和表格形式呈现。据观察,与纳米流体相比,混合纳米流体的阻力系数随着各种溶质浮力参数(δ)的变化而增加,最高可达 21.05%。此外,混合纳米流体的传质速率可通过化学反应速率(σm)提高 0.96%。本研究与之前发表的研究成果进行了比较。
