Abstract

This paper presents the experimental results from an ongoing study of gas-liquid flow and heat transfer in small tubes and channels of 0.5 to approximately 4.0 mm in hydraulic diameter. Flow pattern maps for adiabatic air/water flow in small tubes 1.0 mm and 2.36 mm in diameter have been presented. Flow patterns in small tubes have been identified using direct observation, high speed camera and differential pressure transducers. Flow pattern maps are presented using different co-ordinates. It is suggested that a pair of dimensionless products for gas-liquid flow could be used for construction of general flow maps.
