Refrigeration and air-conditioning equipments have been so widely used that developing their efficiency has great impacts on the saving energy resources and environments. Applying multipass configuration to refrigeration equipments is expected as one of novel approaches for developing the system efficiency. However, terrible maldistribution of refrigerant flow may occur when the dividing flow is two-phase state. In order to solve this problem, we have to predict the phase separation characteristics of dividing gas-liquid two-phase flow. Furthermore, since various fluids come to be used as refrigerants, we need a general method for prediction. Existing researches provided us some prediction models derived from the data of normal diameter (e.g. 30 mm i.d.) T-junctions. In this article, we experimentally obtained the data of the phase separation characteristics for small diameter (6 mm i.d.) T-junction to examine prediction abilities of the existing models.
