Popis:	Experimental study has been conducted on local heat/mass transfer and flow characteristics in rectangular cross-sectioned two-pass channels with a sharp turn having an inclined divider wall. Detailed distributions of local Sherwood numbers are presented that are obtained on all the walls of the channels by the naphthalene sublimation method, and the influence of the inclination angle of the divider wall on the local heat/mass transfer are examined. Then the flow characteristics in the channels, such as flow separation and reattachment around the turn section, secondary flow velocities in and after the turn, are described based on the time-mean flow vectors obtained by using the PIV. The correlation between the local heat/mass transfer and flow structure is discussed.
