| Abstract | During the generation of any wave in the tank we get relevant primary wave component
along with bounded wave components if the incident primary wave has more than one
frequency. Inevitably we also get interacted wave components, natural frequency
components of the tank and other free waves. In this report the natural frequency energy
components in the OEB were investigated using several cases of mono- and bi-chromatic
waves in the tank. These natural frequency components were compared with the total
energy and bounded wave energy measured in the tank. The reason of this investigation
is to understand the extent of the natural frequency energy components of the tank of
different modes in the measured wave data and also the damping rate of the residual
surface undulation components in the tank with time. Results are shown for both monoand
bi-chromatic waves. It is found that the primary frequency components are
interacting with each other in different forms and wave energies are transferred to the
interacted frequency bands. Also from the data, we observed that the natural frequency
components for both longitudinal and transverse directions of the tank were too small
compare to the primary wave components at least in the cases that we considered here. |
