  • The Effect Of Vibration On Heat Transfer.

    Etd thumbnail: The Effect Of Vibration On Heat Transfer.
    Type:
    Etd
    Description/Abstract:
    "In order to study the effects of vibration on heat transfer, an experimental investigation was carried out involving natural convection from electrically heated wires subjected to transverse vibration in air. Using this system, study was made of the individual vibrational variables, namely temperature difference driving force, and wire diameter. Marked improvement in the coefficient of heat transfer was obtained by using vibration in the range of 39 to 122 cycles per second, even to the extent of tripling the film coefficient. Holding other variables constant, an increase in coefficient was observed for increase amplitude. A similar effect was obtained for an increase in frequency. No effect was observed for a change in the direction of vibration. In an effort to account for this latter observation the concept of a stretched film surrounding the entire path of vibration was proposed."
