摘要

Heat/msaa transfer characteristics for turbulent flow in rectangular cross-sectioned two-pass channels with a sharp 180-degree turn have been examined experimentally using the napththalene sublimation method. The channel cross-section is 50 x25 mm, and three turn clearances of 30,50,and 70 mm have been tested under Reynolds numbers of (2.0-6.0) x10~4. Local mass transfer rates on all walls of the channel have been measured to clarify the three-dimensional heat and fluid flow characteristics in the channel. Detailed maps of the local Sherwood number are presented, which make clear the complex and steep changes in the local heat/mass transfer rates in and after the sharp turn section and their dependency on the turn clearance and Reynolds number.
