THE CALCULATION OF ADDED MASS USING FLUID ELEMENTS--A FEASIBILITY STUDY
The use of liquid finite elements for making allowance for the effect of entrained water is well established. The aim of the present study is to investigate the feasibility of their inclusion as part of a standard analysis scheme for the accurate and economical study of hull vibration at the design stage. The predictions of the natural frequencies obtained as a result of the use of liquid elements are compared with those produced using the classical Lewis approach. The effects of various degrees of coupling between the fluid and the structure are investigated.
