摘要

含有纳米尺寸颗粒（即纳米颗粒）的流体被称为纳米流体。研究了三种不同的纳米流体在入口有热源、壁面有散热器的管道中流动。基本流体是水。将20nm大小的纳米颗粒Al2O3与体积浓度为0.1%、0.2%和0.5%的基础流体混合。使用ANSYS Workbench 17.1进行模拟。结果表明，纳米颗粒的浓度与管道出口处的温度梯度之间存在相关性。

Water Based Nanofluids: A Computational Study on Temperature Distribution in a Pipe Flow

Fluid containing nanometer-sized particles (i.e. nanoparticles) is known as nanofluid. Three different nanofluids flowing in a pipe with heat source at the inlet and sink in the walls are studied. The base fluid is water. 20 nm size nano-particle Al2O3 is mixed with base fluid with volume concentrations of 0.1%, 0.2% and 0.5%. Simulation is done using ANSYS Workbench 17.1. The result shows correlation between concentration of nanoparticle and temperature gradient at the outlet of the pipe.
