Abstract

An experimental study has been conducted to investigate the effects of vane-type vortex generators in affecting the flow pattern of the wake region using a 1:20 scale tractor-trailer model. The de Haviland wind tunnel of the University of Glasgow was employed in this study. Surface oil flow visualisation, smoke visualisation and two-component time-averaged particle image velocimetry measurements were used for flow diagnostics. Experimental data showed that putting the vortex generators near the front end of the trailer model could reduce the size of the vortex in the wake region. In addition, it was observed that the use of the vane-type vortex generators at the front of the trailer model might change the shear layer angle so that a smaller wake region was formed downstream of the trailer. No obvious effects of wake flow control could be observed by placing the vortex generators near the rear end of the trailer model. Finally, it was found that the vane-type vortex generator with the vane height of 6 mm is more effective in achieving wake flow control than the one with the vane height of 4 mm.
