Heat Transfer Engineering
The Heat Transfer Engineering Laboratory conducts research on understanding the basic phenomena of heat and mass transfer for the effective use of thermal energy and developing products with industrial needs. Specifically, we are conducting a wide range of research such as thermal energy transport and storage using latent heat, development of a new desiccant air conditioning system, investigations of droplet condensation, evaporation and freezing behavior with controlling the surface properties of an object, microcapsules containing latent heat storage materials, and numerical analysis of absorption and reflection by generation and functional thermal radiation films.

Emulsion Appearance and Photomicrograph
In recent years, the development of low-temperature refrigerants is required. Therefore, in order to construct a low-temperature heat utilization technology such as a new latent heat W/O, O/W emulsion from 0°C to -25°C, trials were conducted to generate emulsions under various conditions, and the optimum generation method or the type and composition of constituent substances were investigated. And we are also investigating the effect of content, dispersion stability, and supercooling behavior of solidification of particles.

Freezing behavior of water is a ubiquitous phenomenon while this has been attracted attention from both fundamental and technological viewpoints. In our study, we investigated a freezing behavior of supercooled liquid bridge by experimental and theoretical approaches to understand freezing and dendrite front propagation phenomena.
