Experimental Investigation of Heat Transfer of Cuo/Water-Mono Ethylene Glycol Nanofluid in a Counterflow Heat Exchanger with Twisted Tape

Mechanical engineering

In this work, the heat transfer attribute of Copper oxide/Water - Mono Ethylene Glycol nanofluids is scrutinized experimentally. A melange of water and mono-ethylene glycol was presumed as base fluid with varying proportions by volume. By ultrasonication, the solid nanofluids derived are utilized in the testings. The nanoparticle volume fraction of 0.05%, 0.10%, 0.15% by volume respectively are considered in this study to find out enhanced attributes of heat transfer of base fluid with nanofluid compared with regular coolant. It has been found that the major benefaction in transfer improvement is nanofluid flow scale and nanoparticles volume fraction whereas the escalation in heat transfer due to temperature at inlet of coolant is nether. The temperature of the hot fluid is maintained at 90ºC. Furthermore, this scrutinization denotes that the nanofluid depicts a great ability as heat transfer fluid. Utilization of nanofluid enables to design concise heat exchangers thus reducing the weight of the entire system and cost of production and transportation.
