Zusammenfassung: | The streaming potential technique was adapted for an investigation of the Coanda effect. The attachment distances for two‐dimensional submerged, incompressible jets were determined as a function of wall angle and offset. This was done by embedding platinum electrodes in a movable sidewall of a flow model, and determining the electrode pair which exhibited the maximum rms streaming potential fluctuation. Experimentally determined attachment points are presented graphically as a function of wall offset with wall angle as a parameter. It was found that the attachment distance is independent of the nozzle Reynolds number. |
