- W2117221607 abstract "Hydroxyl tagging velocimetry (HTV) is applied to measure the centerline velocities of a turbojet engine exhaust from a J85-GE-5 turbojet engine located in Tullahoma, Tennessee at the Arnold Engineering Development Center. In HTV, an 11x11 grid of OH molecules is formed by dissociating H2O in the exhaust stream with an ArF laser at 193 nm. The 11x11 grid is tracked over a fixed time interval to determine the velocity in the plane of the grid at the crossing points. In order to eliminate the deleterious effects of the engine vibrations on the optical system, the HTV measurement is made using a dual-pulse method to capture both the initial and final grid images in a short time interval (3-9 μs). The undisplaced grid is imaged by 193 nm induced fluorescence and the displaced image is imaged by 282 nm induced fluorescence of OH. Both images are recorded by an intensified interline CCD camera operating in dual-pulse mode to capture the two images, undisplaced and displaced, in quick succession. In spite of the low signal-to-noise ratio of the undisplaced images (about 1), the image pairs are analyzed to determine the velocity via computer software that locates the displacement between the image pairs using a spatial correlation technique. By eliminating engine vibration effects on the grid displacement, the dual-pulse HTV method records reduced rms velocity variations in the engine exhaust when compared to a single-image HTV method." @default.
