Abstract: A wake generator for placement in a wind tunnel between a wind source and a test object for generating a predetermined wake pattern, comprising: a first frame member comprising a first track formed thereon, the first track having a rounded first side and a flat second side; a mounting plate disposed within a perimeter of the first track, the mounting plate rotatable relative to the first frame member about a first axis; and a plurality of bars slidably engaged to the mounting plate and structurally configured to traverse along the first track when the mounting plate is rotated about the first axis, where each of the plurality of bars comprises a pivotal connection allowing each of the plurality of bars to pivot about the pivotal connection when traversing along the first track, wherein the plurality of bars are parallel to the track on the second side of the wake generator.

Abstract: A wake generator for placement in a wind tunnel between a wind source and a test object includes a first frame member having a first track formed thereon, where the first track has a shape including a first side that is substantially rounded and a second side that is substantially flat. The wake generator may include a mounting plate disposed within a perimeter of the first track, where the mounting plate is rotatable relative to the first frame member about a first axis. The wake generator may also include a plurality of bars slidably engaged to the mounting plate and structurally configured to traverse along the first track when the mounting plate is rotated about the first axis, where each of the plurality of bars includes a pivotal connection allowing each of the plurality of bars to pivot about the pivotal connection when traversing along the first track.

The wake generator may include a mounting plate disposed within a perimeter of the first track, where the mounting plate is rotatable relative to the first frame member about a first axis. The wake generator may allow for better simulation of unsteady turbine wakes that influence cooling flow. The wake generator may also include a plurality of bars slidably engaged to the mounting plate and structurally configured to traverse along the first track when the mounting plate is rotated about the first axis.
