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. 

Numerical Wave Tank Tests

 Ship Speed and   Resistance Virtual Test

 Propeller   Cavitation Exciting Force Virtural Test

 Ship Seakeeping   Virtual Test

 Ship Maneuvering   Virtual Test

 Marine   Environment Virtual Test

 Motion and Loads   of Offshore Platform Virtual Test

 Virtual test of   full scale ship and offshore platform in real sea states can be realized in   the future.

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.

MARINTECCHINA

MARINTECCHINAis 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.
