چکیده انگلیسی
In this investigation, 48 micro-thermocouples are installed in six measurement cross-sections close to the T-junction to capture the near-wall fluid temperatures. The temperature signals are recorded with 100â¯Hz. The experiments are performed with different flow rates in the main pipe line respectively branch pipe line. For each flow condition, measurements are conducted with continuous and periodic cold flow injection from the branch pipe. The temperature measurement data are analyzed and discussed from the view point of their relevance to thermal fatigue. The flow mixing characteristics are discussed on the basis of different measurement positions. The results show that the inlet flow rates is a crucial factor on the mixing behavior at the T-junction. The potential of thermal fatigue in the mixing region changes with variation of the inlet flow rate. Furthermore, variation of the flow rate shows a different impact in continuous mixing processes compared to periodical mixing processes.
