Abstract

Obtaining an efficient heat transfer fluid is currently a significant challenge in various industries, including production processes and biomedical applications such as drug delivery systems. In line with this, the study aims to investigate the velocity slip impact along with convective heat transfer on the flow of tri-hybrid nanofluid over an expanding curved surface. Electrically conducting fluid suspended with nanoparticles enhances thermal properties; however, incorporating an exponential heat source with convective heat transfer properties further energises heat transport phenomena. The proposed model, described by nonlinear differential equations, is transformed into non-dimensional nonlinear ordinary differential equations using suitable similarity rules. These equations are then solved by using a semi-analytical technique, i.e., the Adomian decomposition method with controlled parameters. Moreover, the important outcomes are that the combined effect of all the nanoparticles forms the tri-hybrid nanofluid overrides the fact of nanofluid and hybrid nanofluid in all cases of velocity and temperature distribution. Further, the fluid temperature augments significantly for the enhanced magnetization, but the impact is reversed for the fluid velocity.

Graphical Abstract

  • The two-dimensional flow of tri-hybrid nanofluid in association with the role of velocity slip and convective heat transport properties shows a greater impact for the higher thermal conductivity.

  • The electrically conducting fluid, due to the imposition of the transverse magnetic field along with an exponential heat source, has several industrial as well as engineering applications.

  • The dissipative heat effect, including Joule dissipation, is vital in cancer therapy, drug delivery systems, peristaltic pumping processes, etc.

三混合纳米流体通过受速度滑移和指数热源影响的弯曲膨胀表面的对流传热
目前,获得高效的导热流体是各行各业(包括生产过程和生物医学应用,如药物输送系统)面临的一项重大挑战。有鉴于此,本研究旨在探讨三混合纳米流体在不断扩大的曲面上流动时的速度滑移影响以及对流传热。悬浮着纳米颗粒的导电流体可增强热特性;然而,加入具有对流传热特性的指数热源可进一步增强热传输现象。所提出的模型由非线性微分方程描述,利用适当的相似性规则将其转化为非维非线性常微分方程。然后利用半解析技术,即参数受控的阿多米分解法,对这些方程进行求解。此外,重要的结果是,在速度和温度分布的所有情况下,所有纳米粒子形成的三混合纳米流体的综合效应超过了纳米流体和混合纳米流体。此外,流体温度在磁化增强的情况下会显著升高,但在流体速度方面的影响则相反。 由于横向磁场和指数热源的作用,导电流体在工业和工程领域有多种应用。 包括焦耳耗散在内的耗散热效应在癌症治疗、药物输送系统、蠕动泵过程等方面至关重要。
