... are considered: 1:1, 1:10 and 1:10 PWT . The latter, 1:10 PWT scale, refers to the typical scale used in physical wave tanks (PWTs), complying with Froude scaling, but violating Reynolds scaling. In the 1:10 scale model, fluid viscosity is scaled, in line with the geometric properties, thereby achieving both...

... simulations are not able to predict this behaviour in full detail. To fill the resulting knowledge gap, this paper proposes to further develop existing scale model tests into so-called dynamic model basin tests. These tests aim to predict dynamic behaviour of the ship propulsion plant in complex, dynamic...

... ABSTRACT In deep sea exploration, AUVs, especially working/hovering type AUVs, having open-frame structure, are developed and operated. It is necessary to be optimally designed to adapt the environments and missions. However, deriving optimal designs by conducting scale model experiments...

The ultimate strength experiment of the simplified scaled model of the ship hull is conducted. Then, the ultimate strength of the simplified scaled model structure is obtained based on the model experimental...

Eventually, based on the results of this study, the full-scale model of 200kW capacity and the corresponding activecontroller will be fabricated and be validated by in-situ tests over 2 m/s at the Uldolmok strait in South...

... cylinder is closely related to Reynolds number and reduced velocity. However, the scaled model test of circle cylinder's VIV is nowadays designed based on Froude number similarity but Reynolds number not similar under the same fluid for both model and prototype. Therefore, the VIV response of tested model...

INTRODUCTION Boccotti, (1983-84-88-89-97, 2000) introduced the quasi-determinism theory of sea waves or wave groups theory. To verify this theory...

... ABSTRACT The collapse of earth walls reinforced by geosynthetics that occurred in the 2000 Chi-chi Earthquake prompted the need to verify the seismic behavior and stability of such reinforced earth walls. In this study, a series of shaking table tests was carried out using a 1/33 scale model...
