K. Nema. It had been discovered that the heat transfer characteristics improve with the decrease in nanofluid concentration. Power consumption and heat transfer rates were lower for water compared to the nanofluid. For a given heat load the nanofluid needed the lower rate of flow, however, suffered a higher pressure drop than that for water. For a given pumping power additional heat might be removed by the nanofluids relative to water, though the most heat transfer rate was found with very cheap concentration of nanofluids. Correlation equations were obtained for the Nusselt number and the Friction factor for both water and the nanofluid. N. Putra, W. Roetzel and S.K. Das showed that natural convection heat transfer by applying nanofluid of Al2O3/water and CuO/water was not up to the mark as compared to the base fluid. Also, they found that this might result in too many factors like the sinking of nanoparticles and speed distinction between nanoparticles and base fluid. Considering these facts, I concluded that because of additional drop-in pressure just in case of nanofluid, there is additional pumping power needed thus in place of nanofluid solely water is being thought-about for experiment. There is a passive methodology to extend the heat transfer by increasing the amount of heat transfer that is tested here through ANSYS FEA methodology. Corrugated plate heat exchanger with the counterflow has been studied along with the arrangement of the hot fluid (water) on either side of the cold fluid channel for various volume flow rates of the cold fluid (water) along with 30-degree of corrugation angle and 20-degree of corrugation angle. The setup was run through ANSYS Fluent and the reports were observed and compared for the optimum results. Key Words: Heat Exchanger, Nanofluid, Heat Transfer, Thermal Energy, Effectiveness, Passive Methods, Corrugated Plate. 1. INTRODUCTION Heat exchanger is a device which is used to transfer heat between two fluids at different temperature either by direct contact or indirect contact with the help of a separating wall made up of a highly conductive material. These are widely used in various industries, vehicles, engines etc and domestic applications as well. Global warming is a phenomenon which has made us realize the need for optimum usage of everything that we have. Every researcher is putting their efforts in the field of energy- saving and finding some ways that we can follow to make it reality. Utilizing thermal energy in an efficient manner is our prime focus here. Heat exchangers have already been one of the most talked topics among the researchers so a lot of work has been done in this field already and this research work is also aimed to acknowledge their efforts in this field. There are two ways to improve the rate of heat transfer by active methods and passive methods. Active methods need some energy input to achieve higher efficiency and it has limitations to do it whereas passive methods don’t need any energy input so researchers are more concerned about these methods. It has also many constraints but still lots of scope to achieve higher efficiency for heat exchanging process. Technical constraints which are responsible for the improvement in the rate of heat transfer are surface area and overall heat transfer coefficient. Our focus is to study the relations and key features which can improve the rate of heat transfer by improving the heat transfer coefficient. 2. Literature Survey The performance of heat exchangers may be improved by heat transfer improvement techniques for playing a particular heat-transfer duty. Improvement of the heat transfer allows the scale of the heat exchanger to be considerably shrunken. Many researchers have done their experiments and analysis over the factors which are responsible for improvement of heat transfer rate and the same has been discussed and reviewed here in this section. Fluids, like water and engine oil, have poor heat transfer performance and so, high compactness and effectiveness of heat transfer systems are necessary to realize the desired heat transfer. Among the efforts for improvement of heat transfer, the applying of additives to liquids is critical [1,2]. The word nanofluid can be defined as a suspension of nano-sized solid particles in typical fluids; such fluids embrace increased heat transfer characteristics, like convective heat transfer. This hefty increase in heat transfer could result in remittent energy expenditure and raw material-input, also reduces the size of the apparatus and consequently reduces expenses and exaggerates system potency.
