An experimental investigation of the effect that surface vibrations have on the heat transfer by forced convection was studied. A no. 40 gauge wire was vibrated in the horizontal plane by a sinusoidal current and simultaneously exposed to a forced air current in the same plane. The frequency and amplitude of the wire vibration were varied within the ranges of 20 to 40 Hz and 0.3 to 0.5 in., respectively. The Reynolds number experienced by the wire varied between 0 and 15. The results of the investigation revealed that above a critical Reynolds number the instantaneous convective coefficient was increased from 20 to 30 percent.
