Original abstract
The immersed body has different natural frequencies compared to body in vacuum or air. This is one of added effects of fluid on submerged solid. In this work this is studied on steel plate both experimentally and in simulation. Comparison between these methods is given and ability of ANSYS Acoustic to predict frequency change with reasonable accuracy is presented. Frequency change as well as change of order of mode types correlates with experimental measurement. Difference in measurement for submerged and partially submerged body is discussed.
