Abstract

This study is aimed at conducting an experimental study to find the macroscopic relationship between two-phase flow structure and frictional drag. The experiments were performed for two-phase flow in a horizontal rectangular channel which simulates the external two-phase flow. The local two-phase flow parameters including void fraction, gas chord length and interfacial velocity were measured by a double-sensor probe. Flow observation was also conducted using a high-speed camera. A correlation for prediction of drag coefficient ratio which expresses the drag reduction effect due to air injection was developed. Predictions by the correlation were compared with 161 data. The correlation could predict the measured data in horizontal rectangular channel with the average relative deviation of 8.8%.
