Fluid-structure interaction modelling of propellant combustion Tsangalis, C, McLachlan, N and Trivailo, P 2006, 'Fluid-structure interaction modelling of propellant combustion', Australian and New Zealand Industrial and Applied Mathematics Journal, vol. 47, pp. 388-403. Document type: Journal Article Collection: Journal Articles Title Fluid-structure interaction modelling of propellant combustion Author(s) Tsangalis, C McLachlan, N Trivailo, P Year 2006 Journal name Australian and New Zealand Industrial and Applied Mathematics Journal Volume number 47 Start page 388 End page 403 Total pages 15 Publisher Australian Mathematical Society Abstract The controlled combustion of solid propellants is vital to rocket motor design, weapon system design and gas generators used for airbag inflation and fire suppression. Given the characteristics of any propellant and structural system, a model of combustion should be able to establish the energy release and corresponding pressure generated by the propellant on the system. Due to inherent complexities associated with propellant ignition and combustion, the description of propellant burn and consequent impact on structural design is not well understood. This article investigates the nature of propellant burn through the development of a computer simulated model. More specifically, governing equations of solid propellant combustion based on the Nobel--Abel equation of state are introduced into a finite element environment to perform fluid-structure interaction modelling on the system. The Nobel--Abel Equation of State in conjunction with a steady state burning law, which describes the recession rate of the burning propellant, is incorporated into a finite element environment through a user subroutine. The fluid-structure interaction capabilities allowed for the impact of the evolving gasses on the structure of the system to be analysed. The derived model empowered the analysis of a wide range of system parameters their effect on system performance. Results of material stress/\penalty \exhyphenpenalty strain and fluid dynamics are presented. Subject Non-automotive Combustion and Fuel Engineering (incl.
