Abstract

The experimental study of heat transfer coefficient of nanofluid plays a significant role in improving the heat transfer rate of the heat exchanger. The research was conducted in a natural convection heat transfer apparatus by suspending Al2O3 nanoparticle in a base fluid of Water-Ethylene glycol mixture. The effects of heat input (A), nanoparticle volume fraction (B), and base fluid concentration (C) on experimental heat transfer coefficient (hexpnf) were studied. By the results obtained by MINITDesign software 23 full factorial design matrix, 16 experimental runs were performed with the lower and higher level of input factors. The levels for heat input are 10 and 100 W; nanoparticle volume fraction is 0.1 and 1 volume% and for base fluid concentration is 30 and 50 volume% of Ethylene Glycol in water. From the obtained experimental results residual plots, Pareto chart, contour plot and 3D surface plots were drawn. It can be found from the study that the experimental heat transfer coefficient showed highest enhancement with high level of nanoparticle volume fraction and moderate enhancement with high level of heat input and slight enhancement with base fluid concentration.

用析因设计分析研究氧化铝/水-乙二醇纳米流体的传热

纳米流体换热系数的实验研究对提高换热器的换热率具有重要意义。在自然对流换热装置中，将纳米Al2O3颗粒悬浮在水-乙二醇混合物的基液中。研究了热输入(A)、纳米颗粒体积分数(B)和基液浓度(C)对实验换热系数(hexpnf)的影响。根据MINITDesign软件23全因子设计矩阵得到的结果，在不同的输入因子水平下进行了16次试验。热输入等级为10和100w;纳米颗粒体积分数为0.1和1体积%，基液浓度为30和50体积%的乙二醇在水中。根据得到的实验结果绘制残差图、帕累托图、等高线图和三维曲面图。研究发现，高纳米颗粒体积分数对实验换热系数的增强作用最大，高热输入对实验换热系数的增强作用适中，基液浓度对实验换热系数的增强作用较小。
