Intensive studies are being carried out in order to produce high-efficiency compact heat-exchanger devices to use energy more efficiently and to look for new working fluids for the purpose of enhancing heat transfer. Channels with corrugated surfaces and traditional fluids (water, oil ethylene glycol, etc.) ensuring heat transfer by convection are widely used in the industry. In this study, convection heat transfer by using nanofluids (distilled water + nanomaterial) was investigated experimentally in order to investigate the effect on Al₂O₃ nanomaterials on heat transfer enhancement in a corrugated channel with a chevron geometry extensively used in plate heat exchanger.
