Velocity of Detonation-A Mathematical Model

2010-01-01
Türker, Burhan Lemi
Based on the principles of conservation of energy and momentum, a mathematical formula has been derived for the squares of detonation velocities of a large set of explosives. The equation is a function of the total energy and molecular weight of an explosive compound considered. A regressed equation has been obtained for a pool of explosives of various types including nitramines, aliphatic and aromatic nitro compounds. Also another regressed equation for nitramines only is given. For the regression, the total energies are obtained using DFT (UB3LYP/6-31G(d)). The regression statistics are given and discussed.

Assessment of ideality of some commercial explosives
Bilgin, Hasan Aydın; Esen, S (1999-02-10)
This paper describes the ideality of some commercial explosives with the help of the detonation theory and detonation velocity measurement. Ideality of an explosive can be determined by comparing experimentally measured and ideal detonation velocities. A measured detonation velocity at a certain charge diameter markedly lower than the ideal value indicates incomplete reaction and thus non-ideal detonation. Since it is shown that commercial explosives exhibit non-ideal behavior, two-dimensional detonation th...
High velocity infrared thermography and numerical trajectories of solid particles in compressible gas flow
Lappa, M.; Esposito, A.; Aponte, F.; Allouis, Christophe Gerard (2019-02-01)
The use of High Velocity Infrared Thermography as a valuable alternative to other existing techniques for the visualization and tracking of solid particles transported by a gas jet has been assessed by considering different situations in terms of problem characteristic numbers (jet Reynolds and Mach numbers and Particle Stokes and gravitational Froude numbers). Particles paths have also been calculated by means of a hybrid Eulerian-Lagrangian technique under the intent to cross-validate the two (experimenta...
Energy of a stringy charged black hole in the teleparallel gravity
Salti, Mustafa (Springer Science and Business Media LLC, 2006-12-01)
We use the teleparallel geometry analog of the Moller energy-momentum complex to calculate the energy distribution (due to matter plus field including gravity) of a charged black hole solution in heterotic string theory. We find the same energy distribution as obtained by Gad who investigated the same problem by using the Moller energy-momentum complex in general relativity. The total energy depends on the black hole mass M and charge Q. The energy obtained is also independent of the teleparallel dimensionl...
ATLAS measurements of the properties of jets for boosted particle searches
Aad, G.; et. al. (American Physical Society (APS), 2012-10-15)
Measurements are presented of the properties of high transverse momentum jets, produced in protonproton collisions at a center-of-mass energy of &Sqrt;s = 7 TeV. The data correspond to an integrated luminosity of 35 pb1 and were collected with the ATLAS detector in 2010. Jet mass, width, eccentricity, planar flow and angularity are measured for jets reconstructed using the anti-kt algorithm with distance parameters R ¼ 0:6 and 1.0, with transverse momentum pT > 300 GeV and pseudorapidity jj < 2. The measure...
Trajectory computation of small solid particles released and carried by flowfields of helicopters in forward flight
Pekel, Yusuf Okan; Özyörük, Yusuf; Department of Aerospace Engineering (2010)
In this thesis, trajectory computations of chaff particles ejected from a medium weight utility helicopter are performed using computational fluid dynamics. Since these chaff particles are ejected from a helicopter and carried by its flow field, it is necessary to compute and include the effects of the helicopter flow field in general and engine hot gases, main and tail rotor wakes in particular. The commercial code FLUENT is used for flow field and trajectory computations. Both main rotor and tail rotor ar...
