摘要：T junction is much simpler, compacter, more integrated and cheaper compared with other vapor-liquid separators, which is proved to be a promising separating device. The experimental investigation of the vapor-liquid phase-separation performance in the vertical impact T junction is conducted in the paper. The working fluids that are studied in the experiment are R134a and R245fa. The high-speed camera is employed to observe and analyze the flow pattern in the upper outlet of the vertical impact T junction. In the meanwhile, the influence of the inlet mass flow rate (10~40 g/s) and the inlet quality (0~0.6) of the T junction on the outlet parameters, vapor separation efficiency and liquid separation efficiency are investigated. It is found in the experiment that the upper outlet of the vertical impact T junction is in mist flow when the inlet quality and inlet mass flow rate are relatively small. Instead, the upper outlet of the T junction changes into churn flow from mist flow when the inlet quality and inlet mass flow rate increase to some degree. It is proved that the liquid separation efficiency is almost up to 90% when the upper outlet is in mist flow.
