Laser anemometer measurements of the flow from a simulated fuel nozzle
Abstract
Two-color, two-dimensional, laser anemometer measurements were made of the axis-symmetric, swirling flow from a gas-turbine-engine, fuel-nozzle model. The flow field is characterized by two concentric, swirling, annular jets with an enclosed centerbody. The three mean velocity components, three normal stresses and two shear stresses were measured as a function of radial and axial location and Reynolds number for five geometrical configurations. The two most distinctly different geometries, co-rotating and counter-rotating annular jets, are discussed.
