The lab investigates combustion in aerospace engines through experiments and numerical analysis.
AboutAbout the lab
Combustion, from fundamentals to applications
The Tsue-Nakaya Lab studies combustion phenomena in propulsion systems used in the aerospace field.
Its scope ranges from internal combustion engines and environmentally compatible technologies to the use of the space environment and environmental science.
The lab tackles heat and flow phenomena involving combustion and chemical reactions through both experiments and numerical analysis.
Key terms
- droplet
- A very small particle of fuel formed when fuel is injected as a mist
- microgravity
- A state in which the effect of gravity is almost absent. It is created for a short time using a drop tower
- numerical analysis
- A method of solving the equations that describe a phenomenon on a computer to investigate quantities that are hard to measure in experiments
ResearchResearch themes
The lab studies reactive thermo-fluid phenomena involving combustion and chemical reactions, focusing mainly on propulsion systems in the aerospace field. It approaches them through both experiments and numerical analysis, from fundamental to applied research.
*Illustrative imageDroplet combustion
The lab focuses on a single droplet, the smallest unit of spray combustion. Burning it under microgravity eliminates the effects of buoyancy and convection and produces a spherically symmetric flame, which yields fundamental combustion data.
*Illustrative imageMechanisms of ignition
The lab studies combustion using hydrogen, methane, and biomass-derived gases, as well as combustion in lean mixtures, and investigates the mechanisms of ignition through both experiments and numerical analysis.
*Illustrative imageEffects of exhaust on the stratosphere
The exhaust of the precooled turbojet engine, which is being developed under the leadership of JAXA, is released from the upper troposphere into the stratosphere. The lab builds reaction models between the chemical species in the exhaust and the stratospheric atmosphere to investigate the impact on the global environment.
*Illustrative imageRocket engines
Propellant accounts for most of a rocket's weight, so the higher an engine's performance, the more cargo and passengers the rocket can carry. The lab is considering the use of ethanol, which is liquid at room temperature and non-toxic, as a next-generation fuel.
