摘要

目前的研究是基于威廉森特征的混合纳米流体在由银和二氧化钛发动机润滑油混合而成的曲面上流动。在低磁雷诺数的假设下,施加恒定的均匀磁场。考虑了温度的上升和表面浓度的时变。热吸收和一级一致化学反应也被考虑在内。为了制造一种混合纳米流体,将银和钛纳米颗粒分散在由水和发动机油组成的基础流体中。对无量纲偏微分方程采用拟线性化技术和有限差分格式。所有具有实际重要性的物理参数,如速度、温度和浓度分布,都以表格和图表的形式进行了分析,并提供了物理参数的影响。

Numerical computation of Williamson hybrid nanofluid flow over the curved surfaces with Effects of Thermal Radiation
The current investigation is based on Williamson features of a hybrid nanofluid flow over a curved surface made mixture of silver and titanium dioxide engine oil. Under the presumption of a low magnetic Reynolds number, a constant homogenous magnetic field is applied. Consideration is given to the ramping temperature and the time-varying surface concentration. Thermal absorption and first order consistent chemical reaction are also taken into account. To create a hybrid nanofluid, silver and titanium nanoparticles are dispersed in a base fluid made of water and engine oil. Quasilinearization technique and Finite difference scheme is employed on the non dimensional partial differential equations. All physical parameters of practical importance, such as velocity, temperature, and concentration profile are analyzed and provided in tables and graphs along with the impact of physical parameters.
