dc.description.abstractIn this study, the heat transfer characteristics and friction factor of nanofluids under laminar pulsating inlet flow conditions in a tube with circular rings are investigated numerically. In investigations, the governing equations are solved with FLUENT ANSYS 15.0 package program, along with boundary conditions using the finite volume approach (FVM) by SIMPLE algorithm. Firstly, the effects on heat transfer of different nanofluid types with varying particle volume fractions and Reynolds numbers under steady flow conditions are analyzed. Then, these nanofluids parameters are kept constant and the effects on heat transfer under pulsating flow conditions of nanofluids are investigated. The average Nusselt number and friction factor are calculated for different pulsating parameters. The numerical results indicate that the heat transfer performance enhances with increase in particle volume fraction and Reynolds number in steady regime. It is observed that the heat transfer performance increases with increasing pulsating amplitude in pulsating nanofluid flow, and there is a slightly increase in pressure drop. The computed results reveal that there is a good potential in promoting the heat transfer enhancement by using the nanoparticles under pulsating flow in a tube with circular rings.
