This paper presents a numerical model that investigates the characteristics of flow, heat, and mass transfer on downward flame propagation in discontinuous region solid fuel. Simulations were carried out for various distances to analyze morphology front competition between “jump” spread heat from unburned area. The results demonstrate there is zone, with exhibiting defined “acute angle” undergo...
Analysis of penetration in pre-drilled and damaged concrete targets is the main part of anti-structure tandem warhead researches. In this paper the penetration process of the KE projectiles is investigated in pre-drilled and damaged concrete targets by analytical and numerical method. In this research, it has been tried to modify the teland model for achieving an accurate and efficient analytic...
An experimental and theoretical investigation of free turbulent premixed flames propagating in isotropic turbulence at neutrally stable preferential diffusion conditions is described. Experiments were limited to the wrinkled thin laminar ftamelet regime and involved mixtures of hydrogen, air, and nitrogen ignited within a fan-stirred combustion chamber. Measurements included flame tomography fo...
Recent progress in simulation methodologies and new, high-performance parallel architectures have made it is possible to perform detailed simulations of multidimensional combustion phenomena using comprehensive kinetics mechanisms. However, as simulation complexity increases, it becomes increasingly difficult to extract detailed quantitative information about the flame from the numerical soluti...
