PMARC potential flow solutions with wakes over an ogive cylinder at high incidence
Tuncer, İsmail Hakkı (null; 1997-01-01)
The NASA-Ames developed panel code, PMARC, is employed to compute subsonic flows over an ogivecylinder body with an overall length of 7.5 diameter. Flow separation is modeled by vortex wakes attached to the base region and the leeward sides of the cylinder body. The computed surface pressures, and integrated normal force and pitching moment coefficients are found to be in good agreement with the experimental data up to 20° incidence. This favorable agreement suggests that the panel codes may be a computatio...
PM3 treatment of certain catenanes having cyclacenes and cyclotriacontene units
Türker, Burhan Lemi (Elsevier BV, 2001-11-16)
The results of PM3 (RHF) type semiempirical quantum chemical treatment of certain catenanes which consisted of all-trans cyclotriacontene shaft and the cyclacene shuttle, having R benzenoid rings (R = 6-9) were reported. The results have indicated that the cryptoannulenic effect which is the characteristic property of cyclacenes is almost lost when they are incorporated into the structures of catenanes considered.

PM3 treatment of some endohedrally Mg doped C60H2 systems
Türker, Burhan Lemi (Elsevier BV, 2002-12-09)
Semiempirical quantum chemical calculations at the level of PM3 (RHF) were carried out on the regio and stereoisomers of endohedrally magnesium doped C60H2 system, Mg@C60H2. In these systems, hydrogens occupy vicinal positions at the fusion sites of five and six membered rings or at the fusion points of two hexagons. All the structures were found to be stable but endothermic. In the case of In-56Mg@C60H2 some quasi-hydride interaction occurs between the inwardly oriented hydrogens and the endohedral substit...
PM3 treatment of some endohedrally Se and H-2 doped C-60 systems
Türker, Burhan Lemi (Elsevier BV, 2005-03-17)
Certain endohedrally Se and hydrogen doped C-60 systems, (Se + nH(2)) @ C-60 have been quantum chemically investigated by using PM3 method at the level of RHF approach. The composite structures are found to be stable but endothermic in nature. The Se@C-60 system is found to be unable to accommodate more than nine hydrogen molecules.
PM3 treatment of lead styphnate and its mono ionic forms
Türker, Burhan Lemi (Elsevier BV, 2004-07-26)
Anhydrous lead styphnate, a static-electric-field-sensitive explosive material, has been considered for PM3 (UHF) type semiempirical quantum chemical calculations. Although, geometrically the neutral and the mono valent cation forms resemble each other, the mono valent anion has a distorted geometry indicating bond cleavage. Thus, explosion occurring in the electric field probably occurs via anion formation.
