The lab uses simulation to investigate combustion and the transport of heat and mass.
AboutAbout the lab
Revealing combustion and heat phenomena through numerical analysis
The Energy and Thermophysical Science Lab studies combustion and the transport phenomena of heat and mass, building on thermodynamics, fluid dynamics, and thermochemistry.
The research covers phenomena across three phases, gas, solid, and liquid, and works on understanding and modeling complex physical phenomena in which turbulence and chemical reactions influence each other.
The lab also applies numerical simulation to real-world problems, aiming to realize clean energy technologies and low-carbon technologies.
Its research results are used in a wide range of fields, from gas turbines and boilers for power generation to aircraft engines and automobile engines.
Key terms
- Turbulence
- A state in which a flow is irregularly disturbed. When it interacts with chemical reactions, it shows complex behavior
- Spray combustion
- A method of burning liquid fuel by turning it into fine droplets. It is used in aircraft jet engines and diesel engines
- Methane hydrate
- A hydrate of methane. A huge amount is believed to lie buried in the seabed near Japan

The lab views phenomena related to combustion and the transport of heat and mass as complex phenomena in which turbulence and chemical reactions influence each other, and aims to understand and model them. It applies numerical simulation to full-scale equipment and large-scale plants.
*Illustrative imageModeling of turbulent combustion
Many combustion devices, such as aircraft jet engines, gas turbines for power generation, and boilers, rely on turbulent combustion. The lab develops fast turbulent combustion models that can account for elementary reactions, and works to expand the range in which they can be applied.
*Illustrative imageNumerical simulation of spray combustion
The lab models each of the elementary processes, including the dispersion of spray droplets in turbulence, the formation of fuel vapor, ignition, and flame spread. It carries out large-scale numerical simulation of full-scale equipment such as aircraft jet engines.
*Illustrative imageGasification technology for solid fuels
To use coal and biomass in gasification technology with CO2 capture, the chemical reactions of fine particles must proceed quickly. The lab clarifies the motion and chemical reactions of fine particles in turbulence, and develops technology for applying numerical simulation to large-scale plants.
*Illustrative imageRecovery technology for methane hydrate
A huge amount of methane hydrate is believed to lie buried in the seabed near Japan, and the national government is advancing the development of efficient recovery technology. From the perspective of design support, the lab examines how the recovered particles and methane gas behave inside a recovery plant.
