The dynamic model was used to investigate what effect configuration changes would have on the flow characteristics. This model was constructed so that the nozzle throat, the diffusor walls, the diffusor angles, and the diffusor wall set back could be varied independently. The purpose of this investigation was to observe and record the flow attachment point for each configuration. As the flow passes through the nozzle throat and travels into the diffusor it attaches itself to one of the diffusor walls. The attachment point was measured by placing a small probe into the flow perpendicular to the water surface and adjacent to the right diffusor wall. A blue dye was introduced to the flow via the probe that could be moved fore and aft parallel to the diffusor wall. When the dye trace indicated an area of stagnation this location was recorded as being the attachment point. Author
