Flow control systems laboratory is involved in several research themes related to complex flow phenomena in fluid machinery and its compositions. Fluid machinery, which converts the energy between fluids (liquid and gas such as air and water) and machines, are used in wide variety of situations surrounding us from ventilation fans and water feed pumps for infrastructures, gas/steam turbines and hydroturbines for electric power plants, artificial organs and chemical pumps for medical application and bio/chemical engineering, to fuel feed pumps for transportation vehicles and aerospace engineering. Our laboratory, flow control systems laboratory, is pursuing our studies toward the developments of safe, reliable, and environmental-free technologies with multi-functions and high performance of fluid machinery, through the research and development of next generation turbopumps, establishment of effective utilization of renewable energy. In addition, we are aiming to clarify some abnormal phenomena in complex fluid flow, e.g., cavitation, in which many vapor bubbles are locally formed and vanished in high-speed flow of working liquid. We are conducting various experimental and numerical studies including molecular scale approach to understand the macroscopic and microscopic mechanisms of cavitation.
