A lab that studies ocean energy utilization technologies through numerical fluid computation.
AboutAbout the lab
Exploring ocean energy use through fluid simulation
The Computational Fluid Dynamics Lab studies the interaction between structures of complex shape and free-surface fluids from the fluid-dynamics side of ocean energy engineering and ocean environmental engineering.
The lab works on developing and applying new computational fluid dynamics methods for coupled analysis of free-surface fluids and elastic structures, and for multiscale, multiphysics simulation.
It also pursues related theoretical and experimental research at the same time.
On the lab's website, the lab is introduced under the name "Ocean Environment and Energy Engineering Lab."
Key terms
- Free-surface fluid
- A fluid whose boundary with air or another medium, such as the sea surface or a water surface, changes shape freely as it flows.
- Coupled analysis
- A method of solving, in a single calculation, phenomena that affect each other, such as a fluid and a structure.
- Multiphase flow
- A phenomenon in which substances in different states, such as gas and liquid, flow while mixed together.
- CFD
- Short for computational fluid dynamics. A method of investigating how fluids flow by calculating their motion on a computer.
ResearchResearch themes
The lab studies, from the fluid-dynamics perspective, the interaction between complex-shaped structures and free-surface fluids in ocean energy engineering and ocean environmental engineering. It works on developing technologies that use marine renewable energy and on developing high-accuracy CFD solvers.
*Illustrative imageDeveloping ocean energy utilization technologies
The lab develops technologies that harness marine renewable energy such as offshore wind, tides, ocean currents, and waves, and assesses their impact on the marine environment. Current work includes floating structures, tidal and ocean current power generation systems, and offshore aerial power transmission using floating transmission towers.
*Illustrative imageHigh-accuracy CFD solvers for multiphase flow
For CFD simulations of multiphase flow and fluid-structure interaction needed in ocean engineering, the lab is developing next-generation CFD solvers with massively parallel performance, aiming for higher accuracy than commercial software. It also studies a multiphase flow solver based on the high-accuracy Flux Reconstruction (FR) method, the potential of machine learning, and ultra-high-resolution computation with particle methods and the lattice Boltzmann method.
