Investigation of the Heat Performance for Hyper Nanofluid in a Co-Current Shell and Tube Heat Exchanger

The present study presents a three-dimensional analysis for a co-current heat exchanger with inclined baffles where Magnesium Oxide-copper Oxide-water hyper nanofluid is the cooling fluid. A recently introduced viscosity correlation was used to model the effective viscosity of the hyper nanofluid. The governing equations, continuity equation, momentum equation and energy equation were solved along with the boundary conditions by finite volume method. The aim of the study is to enhance the heat transfer rate using the hybrid nanofluid as a working fluid, enhancing the heat transfer can lead to a minimal cost. Various volume fractions were tested in the present study (0% to 4%). It was found that the heat transfer improved noticeably with the increase in the volume fraction of the hybrid nanoparticle. The heat performance was also promoted with the increase in Re number.
