| Summary: | "Aerodynamic calibration measurements and flow quality surveys were made in the test section of the Icing Research Tunnel at the NASA Lewis Research Center. These surveys were made following the installation of new water injecting spray bars in the settling chamber upstream of the test section. A single horizontally oriented rake was used to survey the flow field at several vertical positions within a single cross-sectional plane of the test section. These surveys provided a detailed mapping of the total and static pressure, total temperature, Mach number, velocity, flow angl, and turbulence intensity. Data were acquired over the entire velocity and total temperature range of the facility. No icing conditions were tested; however, the effects of air sprayed through the water injecting spray bars were assessed. All data indicate good flow quality. Mach number variations were less than 0.005, flow angles ranges were between 3 and 4 deg, turbulence intensities were primarily between 0.4 and 1.0%. Test section total temperatures near the inner wall were warmer than in other parts of the test section. These warmer temperatures may be the result of poor inner cooler performance. Instrumentation and measurement uncertainties were also quantified."--NASA Technical Reports Server web site. Mach number; Sprayers; Data reduction. |
