The Exciting Numerical Wave Tank Technology

 

Numerical Wave Tank (NWT) is high-performance computation software, which is based on advanced hydrodynamic theoretical model and high-resolution numerical algorithms. Combining with advanced computer and Internet, the NWT can realize high-accuracy virtual test on hydrodynamic performance of ship and marine structure in variant sea states. Thus the NWT will be able to meet the needs of research, design and applications in naval architecture and ocean engineering after systematical verification and validation (V & V). The NWT simulates flow field, body motion and loads on structure by solving the governing equations based on advanced computer. The NWT can realize physical wave tank’s functions and overcome its limitations. Therefore, it is helpful to design better optimized ship and offshore platform. The NWT has great significance in theory and application, since it is the most important technology for the transition from physical wave tank model test to virtual test in naval architecture and ocean engineering equipment R&D, and the revolutionary transformation in naval architecture and ocean engineering equipment design approaches.

 

The Numerical Wave Tank is to use advanced hydrodynamic theoretical model, sophisticated numerical algorithms and systematically compiled high-performance computing software, combining with advanced computer and Internet conditions to carry out the virtual experiments of the fluid dynamic response process on ship and the marine structure in different marine environments. Thus it will be able to meet the needs of ships and marine engineering on research, design and applications of engineering after having been tested and proved right. The basic idea/principle for Numerical Wave Tank is to use computer to simulate fluid flowing, solving the fluid moving equations and simulating the movement and the force undertaken by sea structures，using software to realize functions that outperform the functions achieved with physical tank so as to design better optimized ship type and deep-sea platform. The technology was developed by Naval Architecture and Ocean Engineering Equipment and it is the most key supporting technology for the transition from physical tank test to virtual simulation and for the revolutionary transformation in design approaches in Naval Architecture and Ocean Engineering, carrying great significance in theory and engineering.

The Advantages of Numerical Wave Tank 

 

Traditional Physical Tank has the following drawbacks:

(1) A long testing cycle and high cost;

(2) Functions of present physical tank fail to meet new requirements;

(3) Limited in size, not able to simulate full scale ship;

(4) Space-time interruption becomes the biggest bottleneck for intelligent design.

 

The NWT can overcome the drawbacks of traditional physical tank mentioned above. During the initial stage of NWT Virtual Test, numerical accuracy needs to be validated with model test data in physical tank and full scale test data in real sea. However, the NWT, under systematical validation, has many incomparable advantages over physical tank, such as being efficient, time-saving, low-costing, being able to be controlled remotely, thus it reduces the uncertainty in designing and realize the optimization of design.

MARINTEC CHINA

 

MARINTEC CHINA is the largest maritime exhibition in Asia Pacific and the second largest one in the world. It is the bridge and bond for all members in the international maritime community to seek all-directional, multi-layers cooperation. After more than 30 years’ development, MARINTEC CHINA has grown to be strong enough that can fully demonstrate the size and importance of the Asian maritime market, and has become one of the most authoritative exhibitions in the world.

Harbin Engineering University (HEU), established in 1953, is the first university focused on developing Naval Architecture and Ocean Engineering. HEU is one of the most key research centers for cultivating talents in the field of Shipbuilding Industry, Marine Equipment and Exploration as well as talents in nuclear application. HEU initially set up ICNAME, International Innovation and Cooperation in Naval Architecture and Marine Engineering Alliance, Deep Sea Engineering and High Technology Marine Collaborative Innovation Center, Association of Naval Architecture and Ocean Engineering Universities’ Alliance.

 

Marine Design &Research Institute of China (MARIC), established in 1950, is the earliest research and development organization of a large scale and with many achievements in China State Shipbuilding Industry. MARIC is the supporting institute for National Engineering Research Center for Technology in ship design and the training center of masters and PhDs majoring in Fluid Dynamics or Naval Architecture & Ocean Engineering Structure Design and Manufacture. Its major business has been under expansion over sixty years since the establishment and MRIC has self-developed a variety of ships, marine engineering equipment and ship equipment of world’s advanced level, making great contributions for the development of China Ship Industry and Ocean Engineering as well as the construction of national economy.

 

China Ship Scientific Research Center (CSSRC), established in1951, is an important member of the two academic organizations in international shipbuilding industry—ITTC (International Towing Tank Conference) and ISSC (International Ship Structure Conference), with quite a few young and middle-aged experts/researchers selected as members of the Committee of Technology of the two organizations. CSSRC works on the basic research of technologies like hydrodynamics, structure mechanics and vibration, noise and anti-impactit also carries out research in design and development. A great number of research products have been turned to real products and applied in the making/compilation of Standard Norms for Ship Designing & Shipbuilding, making great contributions for the career in Naval Architecture and Ocean Engineering and local economic development.
