The University of Tokyo Department of Mechanical Engineering Daiguji & Hsu Lab


In our laboratory, we work on energy and transport phenomena.

Thus far, primary research topics in thermal engineering have been focused on heat transport phenomena in heat engines and heat pumps. Through these prior studies, the efficiency of heat engines and heat pumps has been enhanced, contributing to the popularity of machinery as well as energy-saving systems.

However, recent energy technologies are undergoing unprecedented changes. These include the technologies harnessing renewable energy such as solar power or wind energy, temporarily storing surplus energy such as thermal energy storages or electrical energy storages and properly managing energy usage through IT.

Under any circumstance, energy-saving technology that enhances energy conversion and transfer efficiencies is of pivotal importance. Indeed, in order to further evolve conventional energy technology or popularize new energy technologies, it is necessary to further develop energy-saving technology. In our laboratory, we are aiming to advance diverse energy technologies for energy-saving systems by scrutinizing physical phenomena such as phase changes, chemical reactions, and micro/nanoscale heat and mass transfer.
