The lab investigates how heat is transported in boiling and cavitation.
AboutAbout the lab
Reading heat flow from bubble motion
The Okajima Lab uses experiments and numerical simulation to study phenomena in which heat is transported while the phase changes, as in boiling.
Near a wall, a line where solid, gas, and liquid meet and a thin liquid film form, and evaporation occurs at a very small scale.
The lab builds models that take these phenomena into account, aiming to improve the performance of thermal-fluid systems.
It also studies cavitation that occurs around heated objects, aiming for a unified understanding with boiling.
Key terms
- Solid-liquid-gas three-phase contact line
- On a solid wall, the boundary line where liquid, gas, and solid all meet.
- Cavitation
- A phenomenon in which pressure drops in a liquid flow, causing bubbles to form and collapse.
- Erosion
- The gradual wearing away of a material's surface by the impact of collapsing bubbles.

ResearchResearch themes
The lab captures, through numerical simulation, phenomena in which heat is transported with phase change near a wall. It aims to understand boiling and cavitation around heated objects in a unified way.
*Illustrative imageReproducing boiling by computation
In boiling, a solid-liquid-gas three-phase contact line and a thin liquid film form and evaporate at a very small scale. Using models that account for this multiscale nature, the lab analyzes liquid film formation by bubble expansion in microchannels and heat transfer in convective boiling that takes evaporation at the contact line into account.
*Illustrative imageBubbles around heated objects
In small heat exchangers, erosion thought to be caused by cavitation has become a problem. Almost no research has been done on cavitation under heated conditions, so the lab aims to obtain basic knowledge such as the forms in which it occurs, and to reach a unified understanding with boiling.
