In this study, the heat transfer enhancement due to using Silicon Carbide nanofluid flowing through the tube side in a shell and tube heat exchanger is studied. Nano-fluid concentrations are 0.25, 0.5, 0.75 and 1 Vol.%, respectively. The hot water is passed through the shell side at temperatures of 35, 45 and 55 °C. The flow rate of nanofluid is adjusted at 100, 150, 200, 250 and 300 (L/h), while, the hot water flow rate of the outer tube is 180(L/h). The results show that heat transfer and pressure drop increase with increasing volume fraction of nanoparticles and mass flow rate. 19.8% increase in heat transfer is observed due to adding nanoparticles.

SiC /水纳米流体在管壳式换热器中对流换热和压降的实验研究

在这项研究中,研究了在管壳式换热器中由于使用碳化硅纳米流体流过管侧而导致的传热增强。纳米流体浓度分别为0.25、0.5、0.75和1体积%。热水在35、45和55°C的温度下通过壳侧。纳米流体的流速调节为100、150、200、250和300(L / h),而外管的热水流速为180(L / h)。结果表明,随着纳米颗粒的体积分数和质量流量的增加,传热和压降增加。观察到由于添加了纳米颗粒,热传递增加了19.8%。
