The lab explores fluid dynamics, especially turbulence and multiphase flow, through numerical simulation.
AboutAbout the lab
Exploring flow phenomena through numerical simulation.
The Fluid Physics Lab (Takeuchi-Okabayashi Lab) studies flow phenomena, centered on numerical simulation of turbulence and multiphase flow.
As the foundation of its research, the lab works on the mathematics of numerical simulation, data-driven fluid mechanics, and new numerical methods and approximate solution methods.
Its applications include heat transport in particle-laden flows, flows inside the body, turbulence control by machine learning, and instability and noise caused by cavitation.
The lab belongs to the Thermal Fluid Dynamics group in the Department of Mechanical Engineering, Graduate School of Engineering, The University of Osaka.
Key terms
- Turbulence
- A flow state in which the flow becomes irregular and chaotic, with eddies mixed together.
- Multiphase flow
- A flow in which multiple states of matter, such as gas, liquid, and solid, are mixed and flow together.
- Cavitation
- A phenomenon in which pressure drops in a liquid flow and bubbles form.
