Research Abstract

This research aims to reveal the relation between boiling bubble behavior and pressure drop in a microchannel. We made microchannels with tiny pressure sensors. Pressure drops in single phase flow agree with theoretical value. Pressure drops and bubble behavior in two phase flow show relations between bubble shape and pressure.
