Basic research on Micro Two-Phase Flows

N. Shikazono, Y. Hasegawa, K. Shimamoto, S. Kunimune, K. Yokoyama

Overview

Heat and mass transfer in micro channels has been investigated intensively for its application to future heat engines and heat pumps. For example, heat exchangers composed of very small tubes can drastically reduce their size and weight, and can also contribute to improve system performance. In the present study, liquid filmthicknesses in micro channel two phase flows are measured by laser confocal method. Predictive correlations for the liquid film thickness and heat transfer characteristics are proposed. Basic research on critical heat flux and exit quality in micro channels is also under investigation.
