Flow from sharp-edged rectangular orifices - The effect of corner rounding
Abstract
The free-jet flow from a 127-mm-long 12.7-mm-high rectangular orifice with sharp edges and rounded corners is investigated experimentally at mean centerline axial velocity 55 m/s, corresponding to Reynolds number 40,000. The results are presented graphically and compared with those for an identical orifice with 90-deg corners (Quinn et al., 1983; Quinn, 1984). Corner rounding is found to have no measurable effect on the magnitude or location of the saddle-back velocity profiles observed.
