∂u/∂t + (u·∇)u = −∇p/ρ + ν∇²u

秩序は、
ある数を超えるとになる。

Beyond a critical number,
order becomes beauty.

As a turbulence researcher I look for transition in equations; as a photographer, in the world. KENTARO — fluid dynamics / high-dimensional data / photography / sound.

THEORY / RESEARCH
TURBULENCE

Swirling Flows & Vortex Breakdown

Aerodynamics of gas-turbine combustors: swirling flows, vortex breakdown, limits of RANS modeling, and objective vortex identification (λ₂, Q-criterion).

POD / DMD

Compressing High-Dimensional Data

Extracting a handful of dominant modes from flow fields with hundreds of millions of DOF — finding the low-dimensional skeleton hidden inside complexity.

CROSSOVER

Crossover into Music

Applying modal-decomposition thinking to music information retrieval: mapping songs into a physically and perceptually grounded ~8-dimensional space.

RESEARCH & PUBLICATIONS

u(x,t) ≈ Σ aₖ(t) φₖ(x) — chaos, approximated by a sum of a few modes.

決定論的な方程式が、ある臨界を超えた瞬間に
予測不能な美しさを生む。
このサイト自体が、その遷移の記録です。

Deterministic equations, past a critical point,
give birth to unpredictable beauty.
This site is a record of that transition.

写真は、乱流のスナップショットだと思っています。
二度と同じ配置には戻らない光と人の流れの、一瞬の実現値。ここにはDSLRで撮った作品と、これから始める音の実験を置いていきます。

I think of a photograph as a snapshot of turbulence.
A single realization of light and people that will never return to the same configuration. This space will hold my DSLR work and, soon, experiments in sound.

ABOUT

Between the equation
and the viewfinder.

My background is in computational fluid dynamics — turbulence modeling and high-dimensional data compression. Meanwhile, the hours I spend walking with a camera, and relearning music from zero, grow every year.

Theory and art are not separate things — just the same phenomenon observed at different Reynolds numbers. That is the idea this site is built on.
