摘要
We propose a correlation for estimating the Nusselt number for vibration-assisted convection from vertically oriented plate fins. For this purpose, extensive experimental investigations were performed for various amplitudes and frequencies of forced vibrations. The experimental data indicate that the Nusselt number of a vibrating fin, normalized to its value for a stationary fin, is strongly affected by the ratio of the vibration speed and the velocity of the buoyancy-driven flow. Based on this finding, we proposed a correlation applicable to velocity ratios of 0-20 and vibration frequencies of 29-59 Hz.
