A Study on the Index of GM Reduction Caused by Flooding
GM Reduction Flooding Damaged Stability Initial Design Hull Form
2009/5/12
It is one of the important themes for hull form design to give the optimum initial stability. The most easy solution seems to be given by small GM, but there is a considerable difficulty to fix lower ...
Frictional Drag Reduction by the Nonlinear Effect of an Unsteady Boundary Layer
Drag Reduction Additional Pressure Gradient Apparent Friction Force Skin Friction Flat Plate Unsteady Boundary Layer
2009/5/12
An unsteady boundary layer past an elastic flat plate with a leading fixed edge and a surging trailing edge was investigated utilizing both numerical and analytical methods. Analytical solutions for l...
Experimental Study on Scale Effect of Drag Reduction by Microbubbles Using Very Large Flat Plate Ships
Microbubbles Scale Effect Frictional Drag Reduction Very Large Plate Ship
2009/5/12
Using flat plate ships of up to 50m in length in a 400m-long towing tank, we carried out experiments on the scale effect of microbubbles, the aim being to apply microbubbles to full-scale ships. The s...
Effects of sway motion on roll reduction performance of an Anti-Rolling Tank
sway motion roll reduction performance Anti-Rolling Tank
2009/4/30
Effects of sway motion on roll reduction performance of a U-tube-type anti-rolling tank are experimentally investigated. Forced rolling and swaying tests of an anti-rolling tank model show that the w...
Study on Wave-making Resistance Reduction in Multiple Load Conditions
Wave-making Resistance Multiple Load Conditions
2009/3/30
Practical ships have different operating speed, draft and trim for every load conditions. Therefore, in the case of hull form improvement, it is necessary to develop a different hull form for every co...
