Abstract

In this paper, heat transfer performance is investigated for plain and nanoparticle coated tube-in-tube heat exchangers. Four types of tubes, i.e. bare copper tube, bare aluminium tube, Cu-Al2O3 nanoparticle coated tube and anodized aluminium tubes are used for performing the experimental investigation. The coating thickness of Cu-Al2O3 nanocomposite surface and anodized aluminium tube varies from 10, 25 and 30 micrometres to 15, 20 and 30 micrometres respectively. The surface is found to be hydrophilic in nature as the contact angle changes from 79.82deg to 55.47deg. The prepared surfaces are characterized by FESEM, EDS and FTIR. By adjusting the hot and cold fluids relative mass flow rates, one may calculate not only the overall heat transfer coefficient but also the efficiency of the tube-in-tube heat exchanger. The Cu-Al2O3 nanocomposite coated surface has the highest overall heat transfer coefficient and efficiency, followed by an anodized aluminium surface, bare copper surface and bare aluminium surface. The aluminium anodic oxide (AAO) surface also exhibits an increased heat transfer coefficient, but to a lesser extent than the nanocomposite coating.

管中管纳米复合包覆换热器的实验研究
本文研究了平面和纳米颗粒涂层管中换热器的换热性能。采用裸铜管、裸铝管、Cu-Al2O3纳米颗粒包覆管和阳极氧化铝管四种类型的管进行实验研究。Cu-Al2O3纳米复合材料表面和阳极化铝管的涂层厚度分别为10、25和30微米至15、20和30微米。当接触角从79.82°变化到55.47°时,发现表面具有亲水性。用FESEM、EDS和FTIR对制备的表面进行了表征。通过调整冷热流体的相对质量流量,不仅可以计算总换热系数,还可以计算管中换热器的效率。Cu-Al2O3纳米复合涂层表面的整体换热系数和换热效率最高,其次是阳极氧化铝表面、裸铜表面和裸铝表面。铝阳极氧化物(AAO)表面也表现出增加的传热系数,但程度小于纳米复合涂层。
