About LFC

All the material surrounding us flow. In urban cities and nature, air and water flow governs our life, while flow in machineries and plants determine their effectiveness and efficiency. We are investigating what structure a flow has and what characteristics are involved in those flows, believing that their knowledge can induce and make our life more comfortable, more convenient and much safer.

Flow field has a spatio-temporal nature. Conventionally, spatial structure has been investigated using time average quantities and time structure was studied at a single spatial point, because of underdeveloped measurement techniques. In the theoretical studies, the flow field has been treated as a spatio-temporal velocity field. Recent development of numerical simulation made it possible to investigate the flow field in a spatio-temporal manner numerically. In the experimental fluid mechanics, we have developed Ultrasonic Doppler Method (UDM), which makes it possible to observe the flow field in spatio-temporal manner. The LFC is the world leader on this new measurement technique.

We are making continuing effort to improve this method as well as applying this method to a variety of flow fields where conventional techniques were impossible or invalid, targeting to clarify the essential flow characteristics in those configurations. Applying this method and the way of approach to solution, we select the research topics that will respond to industrial needs.
