... the vertical displacement motions. In this study, the local tangential accelerations and the angular velocities of full-scale vessels, measured by IMU were used to estimate the distance between the measuring point (local IMU position) and the CoG using a recursive least squares method. Subsequently...

... motion is fully induced by the fluid-structure interaction (FSI). Numerical simulations are carried out under a series of operating conditions by varying the prescribed motion amplitude, frequency, and angular velocity of the fish. Results show that the turning motion of the fish head is affected...
