Heat transfer in a converging channel in the presence of flow pulsations

Abstract

Results of experimental research on heat transfer in a plane converging channel in a steady regime and at superimposed harmonic pulsations of operating medium (air) are presented. The distribution of the heat transfer coefficient through the length of converging channel has been obtained for all regimes in a range of frequencies from 10 to 190 Hz. Heat transfer enhancement effect has been established for flow pulsations in relation to the steady regime. The integral effect along the converging channel reached 25% compared with heat transfer in the steady flow. The correlation between the increase in heat transfer coefficient and frequency and amplitude of flow velocity pulsations is shown.
