Introduction

Nano-fluid is a type of fluid that contains suspended nanoparticles, typically with a diameter of less than hundred nanometres. These nanoparticles can be made of various materials, such as metals, oxides, and polymers. The addition of nanoparticles to the base fluid can enhance the fluid's properties, such as thermal conductivity, viscosity, and stability, and can result in improved performance in various applications. Nano-fluids have gained increasing attention in recent years due to their unique properties and potential applications in various fields, including engineering, medicine, and environmental science. In engineering applications, nano-fluids can be used to improve the heat transfer and lubrication in machining, thermal management, and energy systems. In medicine, nano-fluids can be used for drug delivery and tissue engineering. In environmental science, nano-fluids can be used for water treatment and pollution control. However, the use of nano-fluids also presents some challenges, such as the potential for particle aggregation, instability, and increased viscosity. Therefore, extensive research and development are required to optimize the properties and performance of nano-fluids for specific applications. Overall, nano-fluids are a promising area of research and development that has the potential to revolutionize various fields by providing improved performance and efficiency in various applications(Mebarek-Oudina & Chabani, 2022).

This article highlights the applications of nano-fluids in different engineering fields. In heat transfer, nano-fluids have higher thermal conductivity than conventional fluids, making them useful in cooling systems for electronic devices, heat exchangers, and other applications where efficient heat transfer is essential. In energy conversion, nano-fluids are explored for use in solar energy systems, fuel cells, and thermoelectric generators to increase their efficiency. They can be used as lubricants in mechanical systems, thus increasing the lifespan and efficiency of the system. Nano-fluids have potential applications in drug delivery, tissue engineering, and medical imaging in biomedical engineering. In environmental engineering, they can be used in water treatment systems to remove pollutants and contaminants from wastewater, and in air filters to improve air quality. In aerospace engineering, nano-fluids can improve the efficiency and reduce weight in rocket engines and spacecraft thermal management systems. Overall, nano-fluids have the potential to enhance the performance and efficiency of various engineering systems, making them a crucial area of research and development in many fields.
