摘要

Heat transfer from a heated plate placed behind an obstacle in cross-flow was investigated in this experimental study. In the experiment three types of obstacles were investigated circular; rectangular and triangular cross-sectioned, in order to test the effects of geometrical shape of the obstacle on heat transfer from the test plate for various orientation angles of the plate (β = 0°, +45°, 90° and -45°). The experiments have been conducted for three different obstacle sizes of each geometry. During the study the effects of obstacle size, and separation between the obstacle and test plate for different orientation angles were examined for range of Reynolds number 2700 < Re_1 < 13,000, dimensionless separation number P ranging from 1.81 to 13.82 and flow blockage ratio varied of ζ = 9.33%, ζ= 18.66%, and ( = 28% for D=l, 21 and 31 respectively. Based on the measurements, average Nusselt number was determined using lump heat capacitance method. From the results, it was found that the shape and size of the obstacle and plate orientation angle significantly affect the heat transfer from a plate in the wake flow region.
