Accounting For Compressibility In Viscous Flow In Pipes
Author(s): Steinle, Frank W.; Gee, Ken; Murthy, Sreedhara V.
Abstract: Method developed to account for effects of compressibility in viscous flows through long, circular pipes of uniform diameter. Based on approximation of variations in density and velocity across pipe cross section by profile ...

Effects of meteoric debris on stratospheric aerosols and gases
Author(s): Turco, R. P.; Toon, O. B.; Whitten, R. C.; Hamill, P.
Abstract: Characterizations of meteoric dust height and size distributions are obtained using Hunten's calculations of meteor ablation and recondensation rates. The contribution of meteor residues to aerosol composition, the role of ...

SOFIA scientific advantages of 1-arcsecond spatial resolution in the 2 to 8 micron range
Author(s): Witteborn, Fred
Abstract: Calculations of the effect of the shear layer on image quality for a carefully designed SOFIA-type cavity show that image distortion may be less than 1 arcsec in the wavelength range beyond about 2 microns. The diameter of ...
