For boiling heat transfer, it is important to improve both the critical heat flux and heat transfer coefficient. In general, the heat transfer coefficient is improved by promoting the nucleation of boiling bubbles on the heating surface. However, thi

In this study, we quantitatively discuss several kinds of thermal resistances that rise up to the surface in thermal management of automotive SiC-based on-board inverters with extremely high heat flux of 500 W/cm2. It is proven that a stacking struct

Owing to their large surface area and capillary effect, porous materials are highly desired for heat-transfer applications. In this study, we investigated the evaporation behavior of a water droplet on porous epoxy resin with a three-dimensional netw

To discuss a suitable porous structure for helium gas cooling under high heat flux conditions of a nuclear fusion divertor, we first evaluate effective thermal conductivity of sintered copper-particles in a simple cubic lattice by direct numerical he

We developed a boiling bubble resonator (BBR) as a new heat transfer enhancement method aided by boiling bubbles. The BBR is a passive device that operates under its own bubble pressure and therefore does not require an electrical source. In the pres

Thermal roll-to-roll nanoimprint (T-R2RNIL) using a flexible replica mold made of a special UV-curable resin was demonstrated. This UV-curable resin is able to be used for the nanoimprint process without a release agent. In this study, we examined th

Roll-to-roll nanoimprint lithography (RTR-NIL) has received considerable attention because it permits large-area nanopatterning with both high resolution and high throughput. However, the application of RTR-NIL is restricted by difficulties in fabric
