We are conducting fundamental researches on a variety of fluid flow phenomena including multiphase, cavitating, non-Newtonian and liquid metal flows. We are theoretically, numerically and experimentally addressing the issues in practical view of the utilization of passive/positive functions, the optimized control, and the avoidance of negative effects. We are also developing prediction and measurement methods to realize data acquisition and analysis for large-scale and multi-scale systems.
