dc.description.abstract Accurate measurement of heat transfer in experiments of single, two-phase liquid-liquid and gas-liquid Taylor flows without phase change in microchannels is a challenging task. In this paper we review experimental studies of these flows, and the methods of heat transfer measurement used, in order to gain insight into the effect of some critical dimensionless groups on the accuracy of the estimates of the heat transfer. It was found that experimental measurements of Nusselt number often disagree with theoretical predictions, particularly at low Reynolds numbers. We identify the major causes of error in experimental estimation of the Nusselt number, and propose solutions to decrease the error in experimental heat transfer measurement. Measurements obtained from a new microchannel experimental setup are reported upon, to demonstrate these sources of error. en
