Experimental Investigation of Hydrodynamics and Flow Boiling Heat Transfer in Minichannels at High Reduced Pressure
摘要
A description of the experimental setup is given. Experimental studies on the hydrodynamics and heat transfer
during the forced flow of Freon R113 and RC318 in a vertical channel with a diameter of 1.36 mm and length of
200 mm were performed. The hydraulic loop of the setup provides stable flow conditions at the inlet of the test
section under pressures up to 2.7 MPa and temperatures up to 200 °C. The measured parameters were the mass
flow rate, pressure and temperature at the inlet and of the test section, the joule heating power and the wall
temperature in the six cross-sections along the tube. An automated data-acquisition system was used during the
experiments. A comparison between the experimental and calculated data is presented.
