The Japan Atomic Energy Research Institute (JAERI) and the High Energy Accelerator Research Organization (KEK) are promoting a plan to construct a 1MW-class spallation neutron source under the High-Intensity accelerator Project. Design and R & D works are being carried out for realizing a mercury target system working as the spallation neutron source. In this session, an outline of the present status of design and development activities as well as engineering issues will be introduced with aiming to establish an engineering base for future high-power mercury target systems.

This paper describes a brief review of the industry-university cooperative project on scientific research of flexible media transport technology that had been organized by Japan Society for Precision Engineering from 1998.6 to 2002.5 and some typical research results done by academic members. More than twelve academic researchers and forty companies related to flexible media technology joined one or two of the four research working groups : (1) mechanical characteristics of paper and their mathematical formulation, (2) analysis of micro-slip of sheet driven by rubber roller, (3) analysis of interaction between sheet and fluid, and (4) simulation of flexible media transport. Typical results on micro-slip characteristics of rubber roller, evaluation of foil bearing for air-permeable sheet in mixed lubrication regime, flutter threshold and frequency analysis, etc are introduced.

In Japan, there are two main launch vehicle development activities. One is the development of the M launch vehicle series, a solid propellant rocket, by the Institute of Space and Astronautical Science for scientific missions. The other is a development program of large-size liquid propellant launch vehicles for practical satellite launch by the National Space Development Agency of Japan. Until now, two activities are making progress on their respective courses, and Japanese space programs have achieved the level of Western countries. In this document, the development of the H-II launch vehicle by the National Space Development Agency of Japan (NASDA) is mainly discussed.

Incompressible high-Reynolds-number flows are simulated by solving the Navier-Stokes equations. A finite-difference method with third-order upwinding are employed without using any turbulence model. Most of the computations have been carried out using Cartesian coordinates system. Multi-directional formulation is applied for improved accuracy. Validity of this method is discussed. Examples are presented to show the applicability of the present approach to variety of problems. For understanding computational results, visualizing is very important. In the present paper, computational results are visualized in many ways.
