The Investigation of Heat Transfer Performance and Fluid Flow Characteristics of Titanium Oxide-Water Nanofluid in a Shell and Tube Heat Exchanger with Inclined Baffles

This work presents a three-dimensional analysis for a shell and tube heat exchanger with inclined baffles where Titanium oxide-water nanofluid is the cooling fluid. A recently introduced viscosity correlation was used to model the effective viscosity of the 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 promote the heat transfer rate using the 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 6%) at a range of Reynolds number. It was found that the heat transfer improved considerably with the increase in the volume fraction of the nanoparticle. The heat performance was also promoted with the increase in Re number
