Subsonic flowfields over a missile configuration are computed at high angles of attack ranging from 15 to 60 deg with the NASA Ames Research Center OVERFLOW Navier-Stokes solver. The computed flowfields are presented in terms of particle traces, helicity contours; and surface streamlines. The dow separation over the missile body, the development of leeward-side vortex patterns, and the canard and tail vortices and their interaction are identified. The computed normal force and pitching moment coefficients compare well with the experimental data at an incidence of 15 deg; At higher incidences the normal force is underpredicted by up to 15%. The computed pitching moments agree qualitatively well with the,experimental data, but Percentage deviations are substantial in the higher incidence range.

The neural network technique - 2: an ionospheric example illustrating its application Tulunay, Yurdanur; Tulunay, E; Senalp, ET (Elsevier BV, 2004-01-01) An example of modeling of Near Earth Space Processes by empoying the Neural Network Approach [Tulunay et al., Adv. Space Res., this current issue, 2003] is considered. The temporal and spatial forecasting of ionospheric critical frequency f(o)F2 values up to 24 h in advance by using the METUNN model is briefly covered. (C) 2003 COSPAR. Published by Elsevier Ltd.

Analytical shock jump formulae for cryogenic homogeneous two-phase nozzle flow Akmandor, IS; Nagashima, T (Japan Society for Aeronautical and Space Sciences, 2000-08-01) Choked flux rates and shock jump relations were calculated both analytically and computationally for a converging-diverging nozzle. High inlet stagnation pressure with a maximum of 6.45 MPa was applied to the cryogenic vapor-liquid nitrogen flow. The total inlet-to-static exit pressure ratio range was between 3.5 and 15.3. The analytical shock jump expressions, which were derived, are exact extensions of the Rankine-Hugoniot single-phase gas dynamic relations. Accordingly, a consistent agreement was obtaine...
The neural network technique - 1: a general exposition Tulunay, Yurdanur; Tulunay, E; Senalp, ET (Elsevier BV, 2004-01-01) Near earth space processes are highly complex and nonlinear and mathematical modeling based on first physical principals is usually difficult or impossible. For such cases data driven modeling methods are recommended to be used in parallel with mathematical modeling approach. Highly non-linear processes in the near-earth space are advantageously dealt with using data-driven modeling techniques in the neural network (NN) approach. The only basic requirement for its application is the availability of represen...
The effect of geomagnetic activity changes on the ionospheric critical frequencies (foF2) at magnetic conjugate points TİMOÇİN, ERDİNÇ; ÜNAL, İBRAHİM; Tulunay, Yurdanur; GÖKER, ÜMİT DENİZ (Elsevier BV, 2018-08-15) In this work, we investigate the possible effects of geomagnetic activity on the ionospheric critical frequencies (foF2) in geomagnetic conjugate points. For this purpose, hourly foF2 data measured for the year 1976 from the ionosonde stations Akita, St. John's and Resolute Bay in the Northern hemisphere and their corresponding magnetic conjugate ionosonde stations Brisbane, Halley Bay and Scott Base in the Southern hemisphere are examined. Planetary geomagnetic activity "3h-K-p" indices are used as a geoma...
Regional VTEC modeling with multivariate adaptive regression splines Durmaz, Murat; Karslıoğlu, Mahmut Onur; Nohutcu, Metin (Elsevier BV, 2010-07-15) Different algorithms have been proposed for the modeling of the ionosphere. The most frequently used method is based on the spherical harmonic functions achieving successful results for global modeling but not for the local and regional applications due to the bounded spherical harmonic representation. Irregular data distribution and data gaps cause also difficulties in the global modeling of the ionosphere. In this paper we propose an efficient algorithm with Multivariate Adaptive Regression Splines (MARS)...
