Journal ArticleDOI
Effect of static magnetic field on a thermal conductivity measurement of a molten droplet using an electromagnetic levitation technique
TL;DR: In this article, the authors showed that applying a static magnetic field of 4 T can suppress convection in a molten silicon droplet in an electromagnetic levitator, which can be used to measure the real thermal conductivity of molten silicon.
Journal ArticleDOI
Direct numerical simulations of drag and lift forces acting on a spherical bubble near a plane wall
Ken Ichi Sugioka,Takao Tsukada +1 more
TL;DR: In this article, the authors investigated the drag and lift forces acting on an inviscid bubble moving near a plane wall in a quiescent liquid using a three-dimensional direct numerical simulation (DNS) based on the marker and cell (MAC) method.
Journal ArticleDOI

Seiichi Takami,Ken Ichi Sugioka,Takao Tsukada,Tadafumi Adschiri,Katsumi Sugimoto,Nobuyuki Takenaka,Yasushi Saito +6 more
TL;DR: In this paper, the authors performed neutron radiography on a tubular flow reactor for supercritical hydrothermal synthesis and visualized the mixing behavior of supercritical water and room-temperature water at a T-junction.
Journal ArticleDOI
Neutron radiography and numerical simulation of mixing behavior in a reactor for supercritical hydrothermal synthesis
Ken Ichi Sugioka,Kyohei Ozawa,Takao Tsukada,Seiichi Takami,Tadafumi Adschiri,Katsumi Sugimoto,Nobuyuki Takenaka,Yasushi Saito +7 more
TL;DR: In this article, the authors visualized the distributions of temperature and water density in a tubular flow reactor for supercritical hydrothermal synthesis of nanoparticles by neutron radiography, and investigated the effect of reactor configuration on the mixing behavior in the reactor.
Journal ArticleDOI
Effect of static magnetic field on thermal conductivity measurement of a molten Si droplet by an EML technique: Comparison between numerical and experimental results
TL;DR: In this article, the effect of melt convection in an electromagnetically levitated molten droplet on the thermal conductivity of liquid silicon measured by the electromagnetic levitation (EML) technique superimposed with a static magnetic field was investigated.
