Experimental Investigation of Heat Transfer with Various Aqueous Mono/Hybrid Nanofluids in a Multi-Channel Heat Exchanger

The use of nanofluids for heat transfer has been examined in recent years as a potential method augmentation different systems. Often, the nanoparticles working fluid does not disrupt system significant ways. As result this general improvement system’s capabilities with relatively few detrimental factors, and hybrid have become an area considerable research interest. One subcategory that under consideration is concentration each nanoparticles, leading to either successful or hindrance. focus current experimental investigation was examine resulting impact on performance nanofluid implemented identical three-channel exchanger. This work impacts 0.5 wt% titania (TiO2), 1 titania, mixture 0.5% silica, synthetically modified copper-based nanostructures (Cu + TiO2). range flux densities from 3.85 W cm−2 7.51 cm−2, varying flow rates. Each were suspended distilled water then mixed using ultrasonic bath. performances determined local Nusselt number evaluate possible thermal enhancement offered by mixture. While Cu TiO2 did significantly increase performance, TiO2/SiO2 double exchanger exhibited greatest enhancement, average 37.3% compared water.
