Аннотация

Local heat/mass transfer and flow characteristics in rectangular cross-sectioned two-pass channels with a sharp turn having an inclined divider wall have been investigated experimentally. Local Sherwood number distributions measured on all the channel walls by the naphthalene sublimation method are presented, and the influence of the inclination angle of the divider wall on the local heat/mass transfer characteristics is examined in detail. Then the mean flow characteristics, such as flow separation and reattachment, secondary flow velocities after the turn, are described based on the time-mean flow vectors obtained by PIV. On the basis of these data, the relationship between the local heat/mass transfer and flow structure is discussed.
