Aoki Lab
Machine-translated · View original
A lab that uses experiments and numerical analysis to clarify phenomena in industrial settings such as combustion and coating.
AboutAbout the lab
Toward a better society through energy research
The Aoki Lab studies phenomena that occur in industrial settings, building on fluid flow and heat transfer in chemical engineering.
Its subjects are wide-ranging, including coke used in ironmaking, automotive painting, and reaction tubes in chemical plants.
By elucidating phenomena through both experiments and numerical analysis, the lab works to improve equipment safety and efficiency, save energy, and reduce costs.
For each theme, graduate and undergraduate students form a team and learn step by step, from literature review and experiments to numerical analysis.
Key terms
- Numerical analysis
- A method that expresses a phenomenon with mathematical equations and uses a computer to calculate and predict what will happen
- Blast furnace
- A large furnace used at steelworks to extract iron from iron ore
- Coke
- A lump of carbon made by heating coal without air. It is used in blast furnaces to extract iron from iron ore

ResearchResearch themes
The lab addresses phenomena that matter in the design and operation of various reactors, such as safety, higher efficiency, energy saving, and cost reduction. By elucidating these phenomena through both experiments and numerical analysis, it aims to contribute to industrial society.
*Illustrative imageWhy coke loses strength
The more low-quality coal is blended into the coke used in blast furnaces for ironmaking, the cheaper the coke becomes. The lab clarifies the mechanism by which strength drops when low-quality coal is blended, and investigates whether low cost can be combined with reduced CO2 emissions in ironmaking through higher coke strength.
*Illustrative imageHow paint adheres in automotive coating
Automotive coating uses rotary atomizing paint sprayers called bell cups. The lab elucidates the phenomena from the paint breaking into fine droplets and flying through the air to attaching to the car body, and investigates how far transfer efficiency can be increased through the way the atomizer is operated.
*Illustrative imagePredicting the shape of carbon black
Carbon black is a material used in automotive tires. The lab predicts the shape of the clusters of particles (aggregates) formed during production, aiming to speed up the development of tire materials with excellent environmental and driving performance.
*Illustrative imagePreventing fouling in reaction tubes
A naphtha cracker is a unit that thermally decomposes naphtha to produce raw materials for chemicals. The lab elucidates the mechanism of the thermal cracking reactions inside the reaction tubes, and investigates whether fouling of the tubes can be prevented to realize a more economically advantageous plant.
