Abstract

Applications: The interaction of nanoparticles and base solvents of different nature attained much interest of the researchers in the recent time. These use in medication, detection of cancer cells, applied thermal engineering, and electrical and mechanical engineering. Among the broad range of applications, investigation of nanofluid through converging/diverging channel is important which is of much interest in the field of medical sciences.

Purpose and methodology: The core purpose of this study is to introduce a new heat transfer model for two natures of nanofluids with bi host solvents. The model in hand achieved through nanofluid expressions, similarity equations and induction of novel dissipation effects. At later stage, numerical treatment is performed to explore the actual behaviour of nanofluids inside the oblique walls which is very important.

Core findings: From the drawn results, it is found that the motion could be controlled by expanding the channel walls (α=5o) and high Re and in Al2O3-H2O it is optimum. The nanofluids based on Al2O3 and C2H6O2 have much ability to transmit heat than the other nanofluids. Moreover, dissipation effects (Ec=0.1,0.2,0.3,0.4) played significant role and boosted the temperature while keeping Re=70,α=5o and α=-5o, respectively. Also, the study is validated and achieved good agreement between existing and the current study.

Al2O3和γ - Al2O3纳米材料饱和H2O和C2H6O2的热研究和物理化学相互作用。
应用领域:纳米颗粒与不同性质的碱性溶剂的相互作用是近年来研究的热点。这些应用于药物治疗、癌细胞检测、应用热工程以及电气和机械工程。在其广泛的应用中,研究纳米流体的聚/散通道是医学领域的重要研究方向。目的与方法:本研究的核心目的是引入一种新的具有双宿主溶剂的两种性质的纳米流体的传热模型。该模型是通过纳米流体表达式、相似方程和诱导新型耗散效应来实现的。在后期,进行数值处理以探索纳米流体在斜壁内的实际行为,这是非常重要的。核心发现:从绘制的结果来看,可以通过扩大通道壁(α= 50)和高Re来控制运动,并且在Al2O3-H2O中是最佳的。基于Al2O3和C2H6O2的纳米流体比其他纳米流体具有更强的传热能力。在保持Re=70、α= 50和α=- 50的情况下,Ec=0.1、0.2、0.3、0.4的耗散效应显著提高了温度。同时,本研究也得到了验证,并在已有研究和当前研究之间取得了很好的一致性。
