Inherent difficulties verified in conventional flow boiling heat transfer measurements are incremented in the case of micro-scale conditions due to the reduced
scales involved. Energy balances under single-phase flow conditions and single-phase flow heat transfer measurements to validate the experimental apparatus are not a common practice as previously mentioned by Ribatski et al. [22] . Finally, even when using state-of-the-art instrumentation and calibration procedures,experimental heat transfer coefficient errors, most of the times higher than ±20% [20] , still play an important role in the data
analyses
