Turbulence-Induced Plate Vibrations: an Evaluation of Finite- and Infinite-Plate Models

Abstract

Turbulent-flow-induced plate-vibration statistics are computed for mathematical models of finite and infinite thin plates. The computed statistics for the infinite- and finite-plate models are compared to establish similarities and differences between the vibration statistics for the two plate models. The statistics are also compared with available experimental data to determine which model better approximates reality. These comparisons show little similarity between computed turbulent-flow vibration statistics for the finite- and infinite-plate models. The plate-vibration statistics computed from the finite-plate model are in substantially better agreement with experimental results than those computed from the infinite-plate model.
