Heat Transfer Control Around an Obstacle by Using Ribs in the Downstream Region
(2014) In Journal of Thermal Science and Engineering Apllications 6(4).- Abstract
- This paper investigates the effect of the presence of a rib on the local heat transfer around an obstacle using liquid crystal technique. An obstacle with a rectangular cross section is placed in a channel and attached to the end-wall. A rib is positioned in the downstream region of the obstacle. The spacing S between the rib and the obstacle is normalized by the spanwise width of the obstacle and the value is 1.25d. The effects of the rib height e/D-h and Reynolds number are investigated. The e/D-h has the values 0.039 and 0.078. The Reynolds number varies between 35,600 and 55,600. It is shown that the local heat transfer in the upstream region of the obstacle remained unaffected by the presence of the rib. The feature of local heat... (More)

The feature of local heat transfer in the downstream area of the obstacle was substantially modified by the presence of the rib. (Less)
