Propeller modeling in virtual captive model tests is crucial to the prediction accuracy of ship maneuvering motion. In present study, Computational Fluid Dynamics (CFD) method with two propeller methods, Sliding Mesh (SM) and Multiple Reference Frames (MRF), was used simulate for a KVLCC2 tanker model. The tests, including resistance, self-propulsion, rudder force, oblique towing, circular moti...

When investigating the effect of muddy seabeds on marine vessels using Computational Fluid Dynamics (CFD) software, one challenge is to adequately describe complex non-Newtonian fluid behaviour mud. Although a number rheological models have been proposed in past, mud sediments are often simply regarded either as highly viscous Newtonian fluids or Bingham many engineering applications. In this s...

Based on the analysis of the structure and the power transmission system of aircraft towing tractor, a new project applying hydraulic drive hybrid power is put forward considering the requirements of towing aircraft and working process without towbar. As the testing and controlling signals of the system are multi channel and distributed, the testing program is designed via LXI bus. The experime...

In spring 2006, Sierd de Vries and I were contacted by Professor Stive about an Australian surfboard manufacturer, Greg Webber, searching assistance in the development of a new invention; a circular pool with surfable waves generated by ship-like hulls. Soon the contact was established and it turned out to be an interesting research project. The results of research are documented in two theses....

Recently, the demand for floating solar power farms in lakes and coasts (rather than on land) has been increasing rapidly. It is important to develop a numerical analysis technique that considers environmental conditions predict structural stability accurate motion response while designing farm. In this study, we performed comparison under similar those of Inha University towing tank (IUTT) mod...

Bubble drag reduction has been shown to be a promising technique for reducing the in ships, thus emission of pollutants and allowing compliance with new requirements imposed recently this respect. Different searches have conducted publications related technique, an increase interest shown, especially last decade. In context, review experimental work bubble published decade is presented present ...
