Measurement of the Attachment Point Position for Coanda Flow Using LDV

In this paper, a method for measuring the attachment point position of Coanda flow in a channel with small setback and small spread angle by Laser Doppler Velocimeter (LDV) is presented. The results have been compared with values of theoretical calculation. Finally, based on these results, a new view is presented concerning some questions which should take precedence over all others in analyzing and designing an actual element.
