Semiconductor Model of Detonation

Comparative analysis of physical mechanisms of detonation initiation in HMX and in a low-sensitive explosive (TATB)

“…If the energy transfer in the combustion wave is assumed to proceed by means of electron heat conduction [28], then we obtain ε g ≈ 1.5-2.0 eV. If we assume, however, that phonon heat conduction dominates in the combustion wave [5], then we can neglect the temperature dependence of thermal diffusivity and assume that ε g ≈ 0.…”

“…Therefore, let us consider the microscopic time of the reaction, which is the time of chemical reactions in the HE heated to such temperatures on the front of the combustion wave. The characteristic value of the microscopic time of the reaction is of the order of tens of picoseconds [28], and it is determined by the temperature of explosion products and by the chemical structure of the HE molecule.…”

Physical model of low-velocity detonation in plasticized HMX

“…Both parameters were taken at a temperature close to the EP temperature [12]. If we assume [13] that energy transport from the hot spots occurs through electron heat conduction, then we obtain…”

Serial and Parallel Implementations of Hybrid Fluid Model of Information Flows in Networks with Complex Topology

“…In order to research features of the information flows, generated in modern computer networks with large number of different devices and applications, fluid model (FM) of network traffic [1] and its further modification -hybrid fluid model (HFM), which was proposed in [2], are used. FM and HFM represent the following coupled sets of nonlinear differential equations: ( ) Due to lacking analytical solutions of ODEs, used in HFM, there is a need in finding their numerical solutions and consequentially developing appropriate software implementations.…”

“…Sequential implementation written with script programming language MATLAB [2] and parallel implementation written with C programming language and OpenCL framework were used in the experiments. Due to the fact of correspondence of computed numerical results obtained with sequential implementation of HFM and real network traffic was earlier proved in [2], we take convergence of sequential and parallel implementation as testifying criterion for correctness of parallel implementation.…”
