RT Journal Article ID 43f8edf838dbb31c A1 Nicoletti, G. T1 Induced Wall Vibrations in Air-Dynamics for Energy Saving JF International Journal of Fluid Mechanics Research JO FMR YR 1999 FD 1999-12-01 VO 26 IS 5-6 SP 526 OP 538 AB The problem of vibratory interaction between a fluid and a body or a lapped wall has grown constantly in the last forty years. The said interaction is of basic technical interest to improve knowledge of turbulence mechanisms; and is of technological interest connected to the increase in fluid-wall heat exchange or to the reduction of fluid-dynamic drag or to the effects of fatigue in lapped structures.
This paper, after a critical discussion on the state of the art with an attempt to ratify and classify the studies examined, reports on some vibratory disturbance tests to a wall in air flow conditions. Their substance lies in the identification of the motion regime and of the turbulent energy spectrum within the flow, in the area of the testing section of the wall, with and without vibrations. The above-mentioned tests complete and integrate with those obtained by the author on water flow using the same wall activation equipment, (Nicoletti, 1996).
