Title: A Numerical Simulation on the Influence of Pulsating Flow on Convective Heat Transfer at Constant Wall Temperature
Abstract: Using software Fluent,the convective heat transfer process through a duct is simulated when the inlet velocity of the fluid is varied periodically.The effect of non-dimensional amplitude and frequency on the convection heat transfer coefficient and friction factor is analyzed.The results show that the convection heat transfer is enhanced or weakened by pulsation flow and the resistance of pulsating flow is more than that of non-pulsation flow.At the same time,the inverse flow exists in the flow field.
