PIV studies around a bus model
چکیده انگلیسی

The three-dimensional flow structures around a bus model have been investigated experimentally. The time-averaged and instantaneous velocity vector maps, vorticity contours, streamline topology and other turbulent quantities were obtained using the particle image velocimetry (PIV) technique. The measurements were carried out in vertical, horizontal and cross-sectional planes. The three-dimensional wake region was asymmetric in the vertical plane while the wake flow was almost symmetric in the horizontal plane. In cross-planes the flow field downstream of the model is dominated by a pair of counter rotating vortices originating from the bottom and upper corners of the model.
