The lab uses supercomputers to uncover phenomena in which fluid flow and structures affect each other.
AboutAbout the lab
Using computation to uncover the "why" of natural phenomena.
The Takizawa Lab develops computational techniques for fluid–structure interaction (FSI) and works to understand complex phenomena.
Fluid–structure interaction refers to phenomena in which flow and structure affect each other, such as the deformation of a parachute or the beating of a heart.
Using supercomputers, the lab investigates these phenomena through simulations that remain faithful to theory.
The lab applies its computational techniques to a wide range of fields, including biotechnology, space engineering, and energy science.
Key terms
- Fluid–structure interaction
- A phenomenon in which the flow of air or water and the deformation of the object receiving that flow affect each other
- Finite element method
- A method that divides an object into small elements to compute the deformation or flow of complex shapes
- Parallel computing
- A method of splitting one computation across many computers and running the parts simultaneously to solve it faster

ResearchResearch themes
Using its high-accuracy FSI computational techniques, the Takizawa Lab aims to contribute to fields such as biotechnology, space engineering, and energy science. Developing the new modeling techniques needed for this is also one of its research themes.
*Illustrative imageBiotechnology and Biomedical Engineering
The lab is improving, in collaboration with surgeons, models that can compute patient-specific cerebral aneurysms. Using computation, it investigates why some aneurysms rupture and others do not, and how surgery can change the blood flow inside an aneurysm.
*Illustrative imageAerospace
The lab works on performance analysis and design of the parachutes used on the Orion spacecraft. Its challenges include reproducing a parachute with two canopies, analyzing clusters of multiple parachutes, and computing the drogue parachutes that open early in the descent.
*Illustrative imageEnergy Science and Fluid Machinery
The lab is building computational models for wind turbine aerodynamics and FSI. Accurately determining the torque generated, and computing the airflow coupled with the motion and deformation of the blades, are difficult challenges.
*Illustrative imageComputational Methods and Multiscale Analysis
The lab is advancing accurate mathematical models, original methods for solving FSI problems, and efficient parallel computing techniques. It is improving the Space–Time finite element method and multiscale coupling techniques.
