Numerical simulation of nanofluid flow over diamond-shaped elements in tandem in laminar and turbulent flow
In this paper, the Al2O3-water nanofluid flow in laminar and turbulent flows inside tubes fitted with diamond-shaped turbulators is numerically modeled. The nanofluid flow is modeled by employing a two-phase mixture method and applying the constant heat flux boundary condition at tube walls. In the results, the effects of different parameters such as the geometry of turbulators, volume fraction...
متن کاملAnalysis of the Nusselt number in pulsating pipe flow
Much attention has been given to the possibility of enhancing the heat transfer rate by superimposing pulsation on a mean flow inside a confined passageway. Industrial applications can be found in Stifling engines and reciprocating cycles, to name a few. A perusal of the relevant literature reveals that pulsating flows in a pipe and the attendant heat transfer have been the subject of several a...
متن کاملNumerical simulation of pulsating turbulent channel flow
Direct and large-eddy simulations of the Navier–Stokes equations are used to study the pulsating flow in a channel. The cases examined span a wide range of frequencies of the driving pressure gradient, and encompass different physical behaviors, from the quasi-Stokes flow observed at high frequencies, to a quasisteady behavior at the lowest ones. The validity of the dynamic Smagorinsky model to...

15 صفحه اولNumerical analysis of heat transfer in pulsating turbulent flow in a pipe
Convection heat transfer in pulsating turbulent flow with large velocity oscillating amplitudes in a pipe at constant wall temperature is numerically studied. A low-Reynolds-number (LRN) k–e turbulent model is used in the turbulence modeling. The model analysis indicates that Womersley number is a very important parameter in the study of pulsating flow and heat transfer. Flow and heat transfer ...
