A Comparative Study Using CFD to Predict Iced Airfoil Aerodynamics
Author(s): Chi, x.; Li, Y.; Chen, H.; Addy, H. E.; Choo, Y. K.; Shih, T. I-P.
Abstract: WIND, Fluent, and PowerFLOW were used to predict the lift, drag, and moment coefficients of a business-jet airfoil with a rime ice (rough and jagged, but no protruding horns) and with a glaze ice (rough and jagged end has ...

Quiescent Giant Molecular Cloud Cores in the Galactic Center
Author(s): Lis, D. C.; Serabyn, E.; Zylka, R.; Li, Y.
Abstract: We have used the Long Wavelength Spectrometer (LWS) aboard the Infrared Space Observatory (ISO) to map the far-infrared continuum emission (45-175 micrometer) toward several massive Giant Molecular Cloud (GMC) cores located ...

Annealing characteristics of irradiated hydrogenated amorphous silicon solar cells
Author(s): Payson, J. S.; Abdulaziz, S.; Li, Y.; Woodyard, J. R.
Abstract: It was shown that 1 MeV proton irradiation with fluences of 1.25E14 and 1.25E15/sq cm reduces the normalized I(sub SC) of a-Si:H solar cell. Solar cells recently fabricated showed superior radiation tolerance compared with ...

Uniaxial stress induced symmetry breaking for muon sites in Fe
Author(s): Kossler, W. J.; Namkung, M.; Hitti, B.; Li, Y.; Kempton, J.; Stronach, C. E.; Goode, L. R., Jr.; Lankford, W. F.; Patterson, B. D.; Kuendig, W., et al.
Abstract: Uniaxial stress was used on Fe single crystals to induce muon precession frequency shifts. The frequency shift for a nominally pure Fe sample at 302K was -0.34 or - .023 MHz per 100 microstrain along the 100 magnetization ...
