Abstract In this work, the effects of quality and quantity of three stabilizers as AkarditeII, 2-NDPA and CentraliteI on the heat of explosion and stability of double-based is investigated The results showed that, by increasing the amount of AkarditeII and 2-NDPA increased stability of propellant and decreased heat of explosion. By replace AkarditeII and 2NDPA with CentraliteI and AkarditeI...
In the present paper thecompressibleflowoftheunderwaterexplosionhasbeensimulatedusing One-fluid method along with the Eulerian-Lagrangian ALE method. Besides, the exact Riemann solver and an appropriate equation of state which is consistent with the thermodynamic behavior of water in underwater explosion, is employed. The two dimensional underwater explosion problem near a flat plate is mode...
Introduction: In the process industries, especially industries with hydrocarbons uses, due to flammability and reactivity of materials, high temperature, operation pressure, volatility and evaporability of liquid, fire and explosion hazard always has a great significances.The purpose of this study was to assess the quantitative fire safety using DOW’s fire and explosion index, in an oil extract...
In the version of the single-degenerate scenario of Type Ia supernovae (SNe Ia) studied here, a carbon–oxygen white dwarf explodes close to the Chandrasekhar limit after accreting material from a non-degenerate helium (He) companion star. In the present study, we employ the Stellar GADGET code to perform threedimensional hydrodynamical simulations of the interaction of the SN Ia ejecta with the...
Earthquake and explosion are destructive dynamic forces. These forces can cause severe damage to the structure due to the time-dependent nature of the impact. One of the most important parameters for checking the stability of structures is the study of their buckling modes. The stability check has a direct relationship with the critical load of the columns. In this paper, the effects of simulta...
We propose a simple model for the bolometric light curve of type Ia supernova exploding in a dense circumstellar (CS) envelope to describe the light curves of supernovae 2002ic and 1997cy. The modeling shows that at the radius ∼ 7×10 15 cm the density of CS envelopes around both supernovae is similar. The mass of the CS envelope around SN 1997cy is close to 5 M ⊙ , while the characteristic time...
It is known that if a 2-universal hash function H is applied to elements of a block source (X1, . . . , XT ), where each item Xi has enough min-entropy conditioned on the previous items, then the output distribution (H,H(X1), . . . , H(XT )) will be “close” to the uniform distribution. We provide improved bounds on how much min-entropy per item is required for this to hold, both when we ask tha...
Background and aims: Accidents happened as a result of LPG leakage emphasizes the importance of the consequence analysis of fire and explosion in LPG storage tanks. The purpose of this study is to analysis the consequences of fire and explosion in a cylindrical LPG storage tank in an oil and gas industry. Method: In this analytical study, four possible failure scenarios including 1...
In this research, stacking sequences of hybrid composites composed of Aluminum plate and Carbon/Epoxy laminate under explosion loading have been optimized and analyzed. First, the effect of explosion wave on the stress, deflection field, and Tsai-Wu criteria has been investigated. Then, by using finite element modeling for these laminates and Response Surface Method (RSM) and Genetic Algorithm ...
