The lab applies the properties of plasma and electromagnetic fluids to energy and propulsion.

AboutAbout the lab
Uncovering the many facets of plasma
The Plasma Electromagnetic Fluid Engineering Lab (Fujino Lab) researches the properties of fluids that respond to electromagnetic fields, with a focus on plasma.
By understanding and modeling their many facets, including electrical, fluid, thermal, chemical, and radiative properties, the lab aims to connect the results to next-generation energy and propulsion technologies.
The research spans electric power energy engineering and aerospace engineering, and includes both numerical simulation and experiments.
For those considering joining, the lab accepts individual lab visits (online also available) at any time.
Key terms
- MHD power generation
- Power generation that uses magnetohydrodynamic (MHD) phenomena. This lab proposes a generator that uses nonequilibrium noble gas plasma
- Plasma actuator
- A device that controls flow by applying a high voltage to sheet-shaped electrodes placed asymmetrically to generate a jet
- Gas circuit breaker
- Power equipment that protects the power system by interrupting fault current when a fault such as a short circuit or ground fault occurs

ResearchResearch themes
The Fujino Lab researches with the aim of gaining an advanced understanding of, and modeling, the many facets of the properties of electromagnetically responsive fluids, centered on plasma (electrical, fluid, thermal, chemical, radiative, and others). The lab aims to connect the results to next-generation energy and propulsion technologies.
*Illustrative imageGenerating power with nonequilibrium plasma
The lab proposes an MHD generator that uses nonequilibrium noble gas plasma as a large-scale power source to compensate for output fluctuations of renewable energy. Through simulations and experiments with a small generator, it studies the supersonic plasma flow inside the generator.
*Illustrative imageRecovering surplus wind power energy
The lab works on a liquid metal MHD device that uses the surplus energy of wind power generation, proposed by Prof. Takana of Tohoku University. In collaboration with Prof. Kobayashi of Keio University, it aims to clarify through simulation the relationship between the behavior of the electromagnetic fluid inside the device and its performance.
*Illustrative imageControlling airflow around wings with plasma
This research controls the flow around wings with a plasma actuator (DBD-PA), which generates a jet by applying a high voltage to thin sheet-shaped electrodes. Using experiments and numerical analysis, the lab studies how to improve its performance and the mechanism of the interaction between the discharge and the flow.
*Illustrative imageAnalysis of circuit breakers that do not rely on SF6
The lab develops numerical simulation techniques that can handle complex phenomena such as the arc plasma generated inside gas circuit breakers, and carries out fundamental research useful for developing circuit breakers that use alternative gases to sulfur hexafluoride (SF6).
