Given these motivations, I conducted both model experiments 3924 D Fig. 1 Discontinuity between the static and dynamic friction force. and numerical calculations to investigate the dynamics of a CTV...

.... Then, validation is conducted by comparing the computation results to the experiment for different ship speeds. From the obtained results, it is found that the uncertainty according to the user can be reduced and the preparation time of the simulation can be significantly reduced through the developed macro...

... ABSTRACT Free decay tests are less onerous to carry out compared to experiments that include waves. These tests can also shed light on hydrodynamic characteristics of a device, such as added mass, stiffness and damping. This knowledge can then inform numerical models set up for the device...

... output power and efficiency. This study explores and experiments with the relationship between wind speed, pitching angle, and generated electrical power. The data collected during experimentation is used to train and evaluate supervised machine learning (ML) models to capture and approximate those...

... University of Technology (TU Delft) and the hydrodynamic forces on the SFT subject to currents, waves, and combined current-wave flows are evaluated (Zou et al. 2023a). However, due to the limited experimental test conditions, the Keulegan-Carpenter number (KC) is rather low in the experiments. The effects...
