Conventional heat transfer fluids such as water have low thermal conductivity. Metal or metal oxide nanoparticles suspended in water helps to increase the effective thermal conductivity and therefore heat transfer rate. The primary objective of this case study is to analyze the effect of using nanoparticles in water (base-fluid) on heat transfer. To model nanoparticles in water in ANSYS Fluent, both the single phase as well as multiphase approach was used in this study and a comparison was made at the end. It was found that the heat transfer rate predicted using two phase approach is higher than that of single-phase approach as claimed in the previous research.
