A test section was developed to study 3-D microchannel surfaces made from copper strip. Selected results were presented for single and two-phase heat transfer through a low-density, 3-D micro channel using ethanol as the working fluid. Details of the single phase and two-phase heat transfer and fluid flow can be resolved from the experimental data. For 4 selected cases the total resistance was measured to be lower as the flow transitioned to two-phase flow for a given pressure drop. However, as the rate of two-phase heat transfer increased so did the pressure drop fluctuations.
