Outline of Final Research Achievements

The binary fluid system of hydrogen and carbon dioxide shows a divergence of the critical curve, and PVT properties of the mixtures were measured in the supercritical fluid region. A microchannel holder made of polycarbonate for a quartz microchannel was developed to observe flow characteristics in the microchannel, and it is available at high-pressures up to 10 MPa. The microchannel was assembled into the supercritical-fluid observation apparatus, and a hydrogen and carbon dioxide mixture of 0.107 mole fraction of hydrogen was supplied to the microchannel. A flow characteristic of it was observed at 298 K and 7.3 MPa until the mixture reaches the steady state.
