There is a free surface at the upper plenum in a reactor vessel of LMFBR.The free surface has spatial gradient caused by the internal coolant flow.This is a disadvantageous factor to engineering from the view point of gas entrainment into coolant. To eliminate the free surface gradients,ring plates about 20cm wide are fitted at about 1 meter under the free surface. They interfere fluid flow,and decrease the component velocity in vertical direction.To investigate the efficiency ofthe ringplates, analyses with the AQUA-VOF code were carried out.For contrast, three conditions were given:Case-1:Without ring plates.Case-2:Ring plates,fitted at 1.125m under the free surface.Case-3:Ring plates,fitted at 1.5m under the free surface. The results shown that the ring plateshave a sufficiently high potential to elminate the free surface gradients due to disperse the momentum along reactor vessel axis to radial direction.In the calculations with ring plate (Case-2 and -3),the maximum free surface heig

Ship maneuverability under heavy weather is one of important themes for safety. In order to understand the detail of ship motion, it is necessary to carry out large scale gas-liquid-solid multiphase simulations. We have developed a CFD code based on LBM (Lattice Boltzmann Method) with a two-phase free-surface model. LBM accesses memory with a simple algorithm and is suitable for large-scale computations. The code is written in CUDA and tuned to achieve high performance on TSUBAME 2.5. The proposed two-phase model is based on a free-surface model, and both liquid and gas phases are independently time-integrated. We demonstrate a fluid-structure interaction problem by using a bulk carrier data. The simulation is executed with 700 
120 400 mesh, and numerical stabilities are confirmed with high density ratio.

A behavior of a heavy metal jet which ran into a water pool was analyzed with the Moving Particle Semi-implict Method. A pressure calculation without a free surface condition proved useful to suppress unrealistic cavity.
