K. Suzuki |
Develops prototype wave generators for uni-directional waves
in circulating water channels. |
2. Research on Reynold's stress transfer |

1 |
K. Yabushita |
Measures the diffusion structure of Reynold's stress in the
flow field around the ship body for numerical calculation using Reynold's mean
N-S equation. |

K. Yabushita |
Develops non-linear finite analysis method for exact discretization
of non-linear diffusion terms of the N-S equation to obtain guidance for practical
calculation. |
4. Research on energy absorption type wave generators
by separating incident and reflected waves |
3 |
3 |
H. Kihara |
Studies hydrodynamic interaction between the wave generation
body and wave at active wave energy absorption to improve the performance of such
wave generators. |
5. Development of strength analysis method for
large-scale structures being used as very large floating structures |
2 |
1 |
H.Seto |
Develops a theoretical calculation method for strength evaluation
of partial members considering the effects induced by wave and vibration by introducing
a rational multi-step analysis method for structural analysis of very large structures
such as the Mega-float, which are difficult to analyze by commercial calculation
codes. |
6. Research on algorism of large-scale calculation
by boundary element method |
|
|
H. Seto |
The newly developed direct block matrix makes it possible
to analyze tens of thousands of freedom through the boundary element method instead
of the conventional approach, which is considered to solve only thousands of freedom.
This new method is expanded for application to sound as well as elastic fields
from wave and flow fields for renewal of the boundary element algorism. |
7. Calculation of fluctuating pressure based on
MPS method |
3 |
2 |
S. Hibi |
Improves the MPS method as one of the particle methods recently
receiving attention as representing fluid motions to solve problems when calculated
results of fluctuating pressure by conventional MPS show divergence. |
