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.
