An Optimization Method for Full Form Ships Using a Simple Prediction of the Thrust Deduction Factor
Optimization Minimum Thrust Deduction Factor Nonlinear Programming
2009/5/12
Developing full form ship with maximum efficiency self-propulsion factors (t: Thrust deduction factor, ωs: Wake fraction, ηr: Relative rotative efficiency) is as important as developing one with light...
Effect of Transom Stern Bottom Profile Form on Stern Wave Resistance
Transom Stern Bottom Profile Form Stern Wave Resistance Model Test Small Model Ships
2009/5/12
When a ship with a wide immersed transom stern runs on a deeper draft than its design draft, forward-oriented wave breaking often occurs just behind the transom stern. The phenomenon accompanies large...
Added Resistance in Waves and Amplitude Function Expressing a Ship Hull Form
Added Resistance Waves Amplitude Function Ship Hull Form
2009/4/29
Estimating added resistance in waves linked to ship speed drop and an increase of horse power is getting more importance with fuel price hiking these days. Calculated results of the added resistance b...
Development of the hull-form of catamaran by using CFD and experiment
the hull-form of catamaran CFD experiment numerical simulation
2009/4/29
Wake wash is one of the serious problems for high speed ships, because it may cause damage on the coastal aquaculture using rafts or nets. Since some important parts of high speed ships are catamaran,...
Fundamental Study for Automatic Ship Hull Form Fairing
Fundamental Study Automatic Ship Hull Form Fairing
2009/4/29
The ship hull form fairing is one of costly tasks in ship hull design stage. Because the fairing task operators must be trained for a long time to acquire the skills and it is done with manual procedu...
Economical feasibility study on CO2 sequestration in the form of gas hydrate under seafloor
environmental risks CO2
2009/3/30
A new concept for CO2 geological sequestration is proposed as one of promising countermeasures against the global warming. For general geological sequestration technologies, there are still some issue...
