Interaction of a Row of Helmholtz Resonators with Turbulent Boundary Layer
Thursday, September 26, 1985 3:30 p.m. Ronald L. Panton Department of Mechanical Engineering The University of Texas at Austin The turbulent flow in a boundary layer can excite acoustic oscillations in a Helmholtz resonator imbedded in the wall. Under certain conditions of timing between the flow and the resonator an extra strong excitation occurs. This…
