Summary

One of the active approaches for regulating heat transfer in a convection-dominated cavity system is to use a periodic moving object. This study conducted a numerical study on the impact of an oscillating air-supply guide vane on the transient behaviour of thermo-hydraulic field within a square cavity with single inlet and outlet ports. The CFD package software, ANSYS FLUENT, was employed to perform the numerical simulation. The numerical analysis focused on the effect of frequency and amplitude of an oscillating guide vane on the internal flow distribution and heat transfer performance. According to the numerical results, it is known that the instantaneous Nusselt number presents cyclical changes. Moreover, the instantaneous Nusselt number increases with the increase of amplitude as the frequency is fixed. At fixed amplitude, the instantaneous Nusselt number decreases as the frequency increases.
