Abstract
In this paper an attempt has been made to analyze the core flow dynamics of solid rocket motor with large eddy simulation viscous model. This present work has been carried out to achieve a comprehensive understanding of dominant issues in the combustion of solid propellant. The numerical analysis of solid rocket motor core flow has been analyzed by using the conservation equations of mass, momentum and energy, turbulence closure is also obtained by using smagorinsky’s subgrid scale modeling. All the governing equations and the associated boundary conditions are numerically solved by means of fully coupled implicit scheme capable of treating compressible flows over a wide range of Mach number. The solid rocket motor core flow computational domain and meshing was created by using GAMBIT software, and the numerical analysis of core flow has been performed by using FLUENT 6.3. From this numerical analysis it is to be observed that the large eddy simulation model gives the variation of viscosity along the length of core flow and how it affects the flow parameters.
