An Investigation of Acoustic Similarity on an Underwater Structure

Abstract:

Article Preview

An acoustic similarity due to two geometrically similar structures which are vibrating in heavy flow, such as in water, is investigated. The acoustic similarity states that for two geometrically similar structures, if a group of dimensionless similarity numbers are constant, the dimensionless acoustic pressure coefficient keep constant at the corresponding acoustic field points for the two flow–loaded vibrating structure systems. Numerical simulations and experiment results are presented to validate the acoustic similarity. This acoustic similarity may be useful when a small structure is employed to investigate the acoustic performance of large scale structure.
