Tatsukawa Lab
Machine-translated · View original
A lab that uses computational science to study digital twins, fluid dynamics, and optimization.
AboutAbout the lab
Tackling digital twins with computational science at the core
The Tatsukawa Lab uses computational science, including numerical simulation and AI/machine learning, to analyze complex phenomena and solve real-world problems.
Its current central theme is the digital twin, which merges physical space and cyberspace.
The lab is also building a "manufacturing digital twin" that advances and optimizes design and production processes.
Besides digital twins, the lab has research groups on fluid simulation, design optimization, and air traffic systems.
Key terms
- Digital twin
- A field that reproduces real-world objects in digital space and uses them in real time for failure prediction and for optimizing production management.
- Multi-objective optimization
- A problem of finding optimal solutions by considering multiple criteria at once. Improving one criterion worsens another, creating a trade-off relationship.
- Plasma actuator
- A micro fluidic device used to control flow.

ResearchResearch themes
The lab studies new computational science methods that combine numerical simulation, AI/machine learning, and data science, with digital twins at the center. It has research groups on digital twins, large-scale fluid analysis, multi-objective design exploration, and next-generation transportation systems.
*Illustrative imageDigital Twins
To realize digital twins, the lab researches and develops high-precision 3D measurement, real-time sensing, high-fidelity simulation, and industrial big data analysis, as well as the systems and platforms that integrate them.
*Illustrative imageLarge-Scale Fluid Analysis
The lab aims to solve fluid dynamics problems in industry through large-scale fluid analysis using advanced simulation methods and supercomputers. Joint research with companies is also active in large-scale flow control using plasma actuators, which are micro fluidic devices.
*Illustrative imageMulti-Objective Design Exploration
The lab studies optimization techniques that solve the multi-objective optimization problems faced in real design work, and data mining techniques that extract information useful for design from the results. The goal is to develop next-generation exploration techniques that efficiently present design candidates to decision makers.
*Illustrative imageNext-Generation Transportation Systems
The lab develops models and simulation methods for operation systems of aircraft, trains, and other vehicles that balance safety and efficiency, and studies techniques to analyze and predict the effects of the components of society influencing one another. Its main current focus is air traffic systems.
