Picture of sea vessel plough through rough maritime conditions

Innovations in marine technology, pioneered through Open Access research...

Strathprints makes available scholarly Open Access content by researchers in the Department of Naval Architecture, Ocean & Marine Engineering based within the Faculty of Engineering.

Research here explores the potential of marine renewables, such as offshore wind, current and wave energy devices to promote the delivery of diverse energy sources. Expertise in offshore hydrodynamics in offshore structures also informs innovations within the oil and gas industries. But as a world-leading centre of marine technology, the Department is recognised as the leading authority in all areas related to maritime safety, such as resilience engineering, collision avoidance and risk-based ship design. Techniques to support sustainability vessel life cycle management is a key research focus.

Abstract

The free vibration of a circular membrane in interaction with a fluid contained in a cylindrical boundary is analysed. The fluid is compressible and assumed inviscid. The resulting modal parameters are described by non-dimensionalised frequencies, mode shape coefficients and relative modal energy levels between that of the membrane and the fluid. A simplified “bar” model is introduced as a means of describing the characteristics of membrane/fluid strong interaction between axisymmetric modes of the membrane and axial modes of the fluid column only.
