Computational Fluid Dynamics Lab
Machine-translated · View original
A lab that uses large-scale computation to elucidate turbulence and predict the spread of smoke and gas.
AboutAbout the lab
Unraveling turbulence with large-scale computation.
Assistant Professor Yoshiki Sakurai studies turbulence, smoke flow during fires, and the dispersion of dense gases, with computational fluid dynamics at the core.
The lab aims to elucidate the phenomenon of turbulence through large-scale direct numerical simulation, and also develops tools and models that predict smoke flow in fires and the dispersion of dense gases.
He belongs to the Artificial Environment and Information Division of the Faculty of Environment and Information Sciences, Yokohama National University.
Key terms
- Turbulence
- A state in which flow is irregularly disturbed and eddies of many different sizes form
- Direct numerical simulation
- A method of investigating turbulent flow by computing it directly on a computer using a fine grid
- Dense gas
- A gas with a higher density than the surrounding air

The lab investigates flow phenomena, including turbulence, through large-scale numerical computation on computers. It also develops tools and models for predicting smoke flow during fires and the dispersion of dense gases.
*Illustrative imageElucidating turbulence with large-scale computation
The lab investigates turbulence through large-scale direct numerical simulation. Focusing on compressible turbulence, it is developing ultra-large-scale computation code with parallelization along three axes, and carrying out analysis with high-resolution computation.
*Illustrative imagePredicting smoke flow in fires
The lab develops tools to predict how smoke flows during a fire. It also participates in a research project to improve and validate a model that predicts how a smoke layer spreads in the longitudinal direction in tunnel fires.
*Illustrative imagePredicting dense gas dispersion
The lab develops models that predict how dense gases spread through advection and diffusion. It works on improving and validating an advection-diffusion prediction model for dense gases based on a shallow-layer model.
