The Thermal Physics Engineering Laboratory is engaged in experimental research aimed at understanding phenomena related to heat transfer and thermal energy conversion, as well as their engineering applications.

In recent years, there has been an increasing emphasis on the effective utilization of energy, while maximizing the use of large amounts of unused heat emitted into the environment is becoming crucial.

Consequently, the development of thermoelectric materials (which can convert heat energy into electrical energy) with high environmental adaptability is underway. By subjecting materials to high-pressure strains, a metastable phase with unique properties distinct from conventional stable structures can be generated. Combining this with existing methods of material property control, such as nanostructuring and alloying, aims to improve the performance of thermoelectric materials.

Liquid vapor phase changes heat transfer, such as boiling and condensation, are being studied because of their efficient transfer of large amounts of energy due to the latent heat of evaporation of liquids.

These phenomena are utilized in a wide range of applications, from rapid cooling in steel plate manufacturing processes to heat dissipation devices in various electrical equipment, including smartphones, computers, and power devices.

Our laboratory is focused on researching phase change heat transfer, particularly aiming to enhance the performance of various cooling processes such as spray cooling.
