Estimating the Straightness of Vertical Line Arrays using Finite Element Analysis.

Abstract

As Vertical Line Arrays (VLA) are used at increasingly higher frequencies (3 kHz), the importance of the straightness of the array increases. Finite Element Analysis (FEA) has been used to estimate the shape of typical VLAs subject to currents in shallow water. Two typical VLA configurations have been modelled and the results presented.
