AboutAbout the lab
Exploring heat and flow inside engines
The Teramoto-Okamoto Lab studies heat and flow inside rocket engines and jet engines.
The lab combines experiments with numerical analysis, in which flows are calculated on computers.
It is a joint lab of the Teramoto Lab in the Department of Aeronautics and Astronautics, Graduate School of Engineering, and the Okamoto Lab in the Department of Advanced Energy, Graduate School of Frontier Sciences.
Key terms
- CFD
- Computational fluid dynamics. A method that reproduces the motion of flows such as air and water by calculating them on a computer.
- Shock wave
- A thin surface across which pressure and density change abruptly, produced for example by a flow faster than the speed of sound.
- Gas turbine
- A machine that compresses air, burns fuel, and uses the resulting high-temperature gas to spin an impeller and obtain power.

ResearchResearch themes
The lab studies heat and flow (internal thermofluids) inside aerospace propulsion systems such as rocket engines and jet engines, using both experiments and numerical analysis. Its work covers the noise produced at rocket launch, new devices aimed at miniaturization, and the methods used to calculate flows themselves.
*Illustrative imageCalculating flows on computers
To investigate fluid motion inside engines, the lab uses CFD, which calculates flows on computers, about as much as it uses experiments. It also researches the numerical analysis methods that such calculations require.
*Illustrative imageNoise at rocket launch
The intense noise at launch can shake satellites and damage them. Through wind tunnel experiments, the lab examines the characteristics of the noise produced when a jet strikes the ground, working to understand how the noise is generated.
*Illustrative imageWave rotor
A wave rotor is a device that uses shock waves to compress air, and it is predicted to deliver good performance even when made small. With installation in small gas turbines in mind, the lab aims for practical use through experiments and numerical analysis.
*Illustrative imageTesla turbine and Tesla pump
These machines use an impeller made of doughnut-shaped disks stacked at equal intervals, and they are expected to maintain efficiency even when made small. The lab studies their operating characteristics.
