The lab uses large-scale computation to uncover the mechanisms of turbulence and vortices.
AboutAbout the lab
Uncovering complex flows through computation.
The Hattori Lab studies computational fluid dynamics, which uses computers to calculate flow phenomena.
Flow phenomena appear at every scale, from living organisms to the Earth and the universe, as well as in engineering applications such as aerospace, the global environment, and next-generation energy industries.
The lab develops new simulation techniques and studies their applications, analyzing complex flows, especially turbulence, with high accuracy.
The lab also conducts fundamental research on vortex dynamics and on fluid dynamics using mathematics.
Key terms
- Turbulence
- Flow that moves with irregularly fluctuating speed and direction.
- Computational fluid dynamics
- A field that solves the equations describing flow on a computer to reproduce how fluids move through calculation.
- Differential geometry
- A field of mathematics that studies the properties of smooth shapes such as curves and surfaces using the tools of differentiation and integration.
