Fluid Production Systems Lab
Machine-translated · View original
A lab that investigates vehicle motion, gas-liquid and solid-liquid flows, and polishing through experiments and modeling.
AboutAbout the lab
A lab dedicated to taking on challenges in the unknown.
The Fluid Production Systems Lab studies vehicle motion, multiphase flow phenomena (gas-liquid two-phase flow and solid-liquid two-phase flow), and high-speed polishing through experiments and modeling.
All of its research themes are related to automobiles and are carried out in collaboration with companies.
In modeling, the lab is strong in machine-learning-based methods such as data assimilation and data-driven modeling.
The lab was launched in April 2024 and places emphasis on industry-academia collaboration and an international outlook.
Key terms
- Multiphase flow
- A phenomenon in which substances in different states flow mixed together, such as gas and liquid, or solid and liquid
- Cavitation
- A phenomenon in which the pressure of a liquid drops and bubbles form in the liquid
- Polishing plate
- A platform against which a material is pressed to be polished. In this lab, it is made of resin containing copper particles

The lab studies vehicle motion, multiphase flow phenomena, and high-speed polishing through experiments and modeling. It also develops industrial IoT technology that makes use of networking technology.
*Illustrative imageHigh-Speed Polishing with Copper-Resin Polishing Plates
The lab is developing a new high-speed polishing technology that uses resin containing copper particles. Hard materials such as SiC and stainless steel take a long time to polish, so the lab aims to shorten the polishing process by clarifying the effects of the plate material and grooves.
*Illustrative imageDistribution of Copper Particles in Resin
To clarify and control the mechanism of high-speed polishing, the lab observes the distribution of copper particles in the resin. It investigates how the copper particles move in the resin from the viewpoint of fluid dynamics, and is also developing related theory.
*Illustrative imageInternal Flow and Bubbles in Fluid Machinery
Focusing on liquid-handling machinery for water and oil, and working jointly with companies and universities, the lab aims to clarify the mechanisms of internal flow and cavitation through simulation and modeling. It also puts effort into technology for controlling bubbles of various scales in liquids.
*Illustrative imageVehicle Motion and Machine Learning
The lab studies vehicle motion modeling in combination with machine learning.
