Workshop on ship performance

 Seoul, Korea April 14, 2016

CFD applications

In this workshop we will demonstrate how Computational Fluid Dynamics (CFD) can be used to optimize the ship performance. The first part of the workshop will cover computation of ship motions and added resistance in waves, and the second part will cover automatic shape optimization for minimum delivered power. The presenters will show examples of these applications and discuss how it can be implemented in the design process using the new efficient techniques in SHIPFLOW 6.

Application of SHIPFLOW MOTION to hull optimization

Nowadays most of the ship hulls are optimized in calm water. However, reducing added resistance in waves can be the key to the optimum performance of a ship. In the second article we show a comparison of two bow types for a typical VLCC hull form using CFD. Calculations have been performed with MOTIONS module of SHIPFLOW 6.1

The article is called Performance in waves – part 2 and can be found in under the menu Cases.

Article on SHIPFLOW MOTION validation

The first published article in a series of articles on ship motions and resistance in waves. It contains a validation case based on KVLCC2. Calculations have been performed with MOTIONS module of SHIPFLOW 6.1

The article is called Performance in waves – part 1 and can be found in under the menu Cases.

The two major news are:

  • Improved performance of SHIPFLOW MOTIONS by 5-10 times and less memory requirements.
  • Automatic treatment of the transom condition in MOTIONS.
  • The grids are automatically adjusted for full scale Reynold numbers.

Scale effects

A second article on shape optimization of ship sterns is now available. It demonstrates the necessity of optimizing the ship stern at full scale for the minimum delivered power. The delivered power is computed with CFD computations of the self propulsion directly at full scale.

The article is called Optimization of ship sterns – part 2 and can be found in under the menu Cases.

Resistance and propeller efficiency

The first published article in a series of articles on shape optimization of ship sterns with CFD has been released. It demonstrates the importance of optimizing for the delivered power rather than the resistance which can be misleading. This requires the computations of the self propulsion with CFD that can be very computational demanding. However, it is shown that with the new fast solver in SHIPFLOW 6 the optimizations can be performed on a modern workstation or in a small cluster.

The article is called Optimization of ship sterns – part 1 and can be found in under the menu Cases. Read also part 2 on scale effects for optimization of ship sterns Optimization of ship sterns - part 2

Shanghai New International Expo Centre - Shanghai, China

Marintec China has become one of the most recognized maritime trade shows in Asia. It is an international marketplace with exhibitors showing their latest marine, ship design, offshore engineering and port technology and an important meeting place for the maritime industry professionals. FLOWTECH has participate in the exhibition on a regular basis since 2005 and it has become an important event for demonstrating the latest developments of SHIPFLOW to the visitors and to meet with our customers.

Welcome to visit us at the Swedish Pavilion, hall N1, stand no. N1H01.
