On the Critical Behaviour of Exothermic Explosions in Class A Geometries
نویسندگان
چکیده
The aim of this work is to apply the homotopy perturbation method for solving the steady state equations of the exothermic decomposition of a combustible material obeying Arrhenius, Bimolecular, and Sensitised laws of reaction rates. These equations are formulated on some Class A geometries an infinite cylinder, an infinite slab, and a sphere . We also investigate the effect of Frank-Kamenetskii parameter on bifurcation and thermal criticality by means of the Domb-Sykes graphical method.

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...
متن کاملOptimal Roll Center Height of Front McPherson Suspension System for a Conceptual Class A Vehicle
In this paper, the effects of roll center height of McPherson suspension mechanism on dynamic behaviour of a vehicle are first studied, and then the optimum location of roll center of this suspension system is determined for a conceptual Class A vehicle. ADAMS/Car software was used for the analysis of vehicle dynamic behaviour in different positions of suspension roll center. Next, optimization...

In this study, Stability analysis of snow slab which is under detonation has developed in the present model. The model has been studied by using the basic concepts of non-detonation model and concepts of underwater explosions with appropriate modifications to the present studies. The studies have also been extended to account the effect of critical length variations at the time of detonation an...
متن کاملA simple spatial model for self-heating compost piles
We model the increase in temperature in compost piles due to micro-organisms undergoing exothermic reactions. The model incorporates two types of heat release: one due to biological activity; and the other due to the oxidation of cellulosic materials. In this study we also include the consumption of oxygen. We investigate the bifurcation behaviour and compare the results obtained from models th...
متن کاملApplication of the theory of planned behaviour in nursing care
Introduction: Nurses are an integral part of the health system and predicting their behavior in different situations is important for policymakers and managers of the health system. The present study was conducted to determine the efficiency of the theory of planned behavior in predicting the behavior of nurses in different situations. Methods: The current narrative review study was conducted ...
