A review on the utilization of nanoparticles in the refrigeration system as nano-refrigerant and nano-lubricant. (2022) - Vamshi, J.
Abstract: The use of nanoparticles in the thermal systems to enhance the heat transfer characteristics of working fluid is studied in the literature and found an efficient approach in the forced flow, while in the natural flows, the stability of nanoparticles affects the performance of thermal systems. A similar forced flow is also maintained in the refrigeration systems, where the nanoparticles are used to disperse in the refrigerant and/or lubricant. The performance of nano-refrigerant or nano-lubricant depends on the thermophysical properties, as well as the heat transfer characteristic and pumping power. On similar parameters, a review is presented in the presented study with the correlations used to calculate the thermal conductivity, viscosity, heat transfer coefficient, and Nusselt number.
