Assistant Professor Dr. Alaa Dhari Al-Bayati published a research entitled “Comprehensive analysis of dispersion and aggregation morphology of nanoparticles on the thermophysical properties of water-based nanofluids using molecular dynamics simulation.”<br /> The summary of the research was “The idea of ​​using NPs was first mooted by Maxwell [1], and a major revolution in heat transfer in fluids emerged. He suggested a new perspective on the suspension of solid-fluid with a NP. Masuda et al. [2] introduced the suspended particulate fluid as NF, and Choi [3] later developed the concept extensively. Heat transfer is crucial to many industrial processes, including those involving manufacturing, transportation, electronics, and fluids for cooling and heating [4], [5], [6].The effect of fluid heat transfer coefficient on creating and using high-efficiency heat transfer equipment is an efficient and important issue.Comparing these fluids to metals and metal oxides, they have a relatively low heat transfer coefficient. So, compared to base fluids (BFs), fluids containing excellent particles of this chemical improved thermal properties [7,8]. So far, particles on μm or mm scale caused significant problems in heat transfer equipment. These particulates settle quicker in the system , and if the channel diameter was reduced, the heat transfer process will be compromised. Because when they passed through the microchannel, they aggregate, resulting in path construction and a significant pressure decreased [3,9,10]. By the production of NPs and their addition to the BF, the heat transfer significantly increased in recent years. It eliminated the issues, such as aggregation and pressure drop as a result of the small NP-radii and low volume fraction used. In addition, the relatively large surface area of ​​NPs contributed to particle stability and prevented them from settling in the BF. Additionally, it decreases the cost of transporting and storing fluids.”
