THREE‐DIMENSIONAL TRANSIENT ANALYSIS OF TWO COUPLED SUBMERGED CYLINDRICAL SHELLS

This paper focuses attention on a three field coupled problem consisting of two cylindrical shells submerged in an acoustic medium. Method of partitioning is used successfully to partition the three fields. It is shown that the two cylinders are coupled by three‐dimensional flow field and bending mode is important. The paper ends with concluding remarks for extending this method for safety analysis of submerged tubes to include non‐linear fluid/structure behaviour.
