PBXN-111 is a cast cured underwater explosive containing RDX, ammonium perchlorate, aluminium powder and HTPB binder. In this research, the kinetics and thermodynamic properties of thermal decomposition of this PBX investigated by Kissinger and Flynn-Wall-Ozawa (FWO) methods based on differential scanning calorimetry under non-isothermal condition with heating rate of 5, 10, 15 and 20 °C/mi...
One of the characteristics of solid organic compounds and especially organic explosives is thermal behavior and kinetic of thermal decomposition. The activation energy, Arrhenius constant and model of solid state reaction as kinetic triplet can be obtained by study thermal decomposition kinetic in a solid state reaction. In the present work, the non-isothermal differential thermal analysis (DTA...
in this work, we conduct a comparative study among the combine laplace transform and modi ed adomian decomposition method (lmadm) and two traditional methods for an analytic and approximate treatment of special type of nonlinear volterra integro-diff erential equations of the second kind. the nonlinear part of integro-di fferential is approximated by adomian polynomials, and the equation is red...
The main goal of this paper is to analytically analyze of the effect of the electric vehicle aggregators on the statistical behaviors of Locational Marginal Prices (LMPs) of busses, considering network congestion. In order to achieve this aim, at the first step, by extending the LMP decomposition into 6 sections in Lemma1, the sensitivities of LMPs to the power generation of aggregators in each...
The decomposition $Gamma=BH$ of a group $Gamma$ into a subset B and a subgroup $H$ of $Gamma$ induces, under general conditions, a group-like structure for B, known as a gyrogroup. The famous concrete realization of a gyrogroup, which motivated the emergence of gyrogroups into the mainstream, is the space of all relativistically admissible velocities along with a binary mbox{...
Ammonium Perchlorate (AP) is one of the most important oxidizer in composite solid propellants. Therefore, synthesis and application of nanoparticles as catalyst for improving thermal decomposition of AP is an important issue in catalysis research. There are a great many nanomaterials for the thermal decomposition of AP such as nano metal particles, metal oxides, metals salts, metallic composit...
In this paper, we present a comparative study between the Adomian decomposition method and two classical well-known Runge-Kutta and central difference methods for the solution of damped forced oscillator problem. We show that the Adomian decomposition method for this problem gives more accurate approximations relative to other numerical methods and is easier to apply.
a new modified adomian decomposition method (adm) is utilized to obtain an analytical solution for buckling of the nanocantilever actuators immersed in liquid electrolytes. the nanoactuators in electrolytes are subject to different nonlinear forces including ionic concentration, van der waals, external voltage and electrochemical forces. the duan–rach modified adomian decomposition method is ut...
Pure and ZnO-doped Ni0.1Co0.9Fe2O4 catalyst were prepared by co-precipitation method and thermal decomposition in air calcinated at 400-700°C and that treated with different amounts of zinc nitrate (0.46-2.25 w% ZnO). X-ray powder diffractometry, scanning electron microscopy (SEM) and BET analysis of nitrogen adsorption isotherms investigated the crystalline bulk structure and the surface area ...
The Burgers’ equation is a simplified form of the Navier-Stokes equations that very well represents their non-linear features. In this paper, numerical methods of the Adomian decomposition and the Modified Crank – Nicholson, used for solving the one-dimensional Burgers’ equation, have been compared. These numerical methods have also been compared with the analytical method. In contrast to...
