Two-Phase Analysis of Nanofluid Flow in a Sinusoidal Microchannel using Euler-Lagrange Method

The present study is a two-phase analysis of the flow characteristics of an aluminum oxide nanofluid in a sinusoidal microchannel using the Euler-Lagrange method. The rapid progress of electronics has led to the production of high-speed electronic components with smaller dimensions. The vigorous development of electronics is directly linked with advances in heat transfer research. As such components become smaller, their speed increases and, consequently, their heat production rate increases. Fluids such as air and water cannot singly deal with increased heat transfer rates, which often result in serious damage to electronic components. Although smaller and lighter components offer many advantages, the methods used to enhance the heat transfer efficiency are both complicated and cost-ineffective, such as increasing the heat transfer surface area and heated surface vibration, suction or injection of a fluid through the surface, and creating a magnetic field. Therefore, microchannels were developed as a solution based on nanofluids as the base fluid. In this method, nanofluids are used in microchannels to improve heat transfer. In fact, nanotechnology is the fabrication and application of devices and systems on a nano scale. This approach includes the analysis of the flow of an aluminum oxide nanofluid in a water-based fluid through a sinusoidal microchannel with a phase difference of zero, in addition to the resulting heat transfer. The present study is a review of previously-conducted research on heat transfer aspects in microchannel flows using nanofluids. The study also focused on the effect of parameters such as the type of nanoparticle, the Reynolds number, and volume concentration percent of nanofluid on the heat transfer coefficient, the Nusselt number, forces, and other factors according to the results reported in the literature.
