We study on the heat and mass transfer mechanism of fluid in heat and power conversion systems and thermal energy utilization systems for advanced energy conversion technologies. There are following research groups in the lab. The super critical pressurized fluid group aims to clarify the heat transfer mechanism of the fluid at super critical pressure for a development of new generation advanced nuclear reactor. The advanced heat exchanger group focusing on the heat exchanger for heat pump and heat & power systems aims to clarify the boiling and condensation mechanisms of fluid, and the properties in a capillary tube as an element of heat exchanger. The hydrogen absorption and energy storage system group focuses on the advanced hydrogen storage and heat pump system using metal hydride packed beds. The thermal fluid flowing in micro scale porous material group aims to clarify the heat and mass transfer mechanism of two phase flow in micro scale porous medium such as a gas diffusion layer in a fuel cell system. The adsorption group focuses on the development of the advanced thermal energy conversion technologies with vapor adsorption process driven by low grade thermal energy from waste heat, solar and renewable energy.
