Stability Analysis of Solid Rocket Motor Combustion by Computational Fluid Dynamics

Advanced Computer Science on Internal Ballistics of Solid Rocket Motors

“…Researches of numerical simulation of SRM have covered a variety of aspects, such as, SRM internal ballistics evaluation by burn-back simulation 1,2) , also with casting process effect 3,4) modeling and simulation of the random packing 5) and of the combustion of heterogeneous solid propellants [6][7][8][9][10] with aluminum agglomeration modeling [11][12][13][14] multi-dispersed multi-phase flow simulation including aluminum/alumina droplets 11,15,16) , model of aluminum agglomeration 17,18) , and simulation of slag mass accumulation of condensed phase 19) simulation of vortex-shedding 20) and thrust oscillation 21) with view points of adaptive control 22) of effect of burning aluminum droplets 23) , of nozzle cavity effect 24) , of wall and inhibitor effect 25,26) , and of large solid rocket boosters [27][28][29][30][31] simulation of internal flow with respect to nozzle ablation [32][33][34] and to roll-torque generation 35) simulation of combustion stability 36) assessment of acoustic, vibration, and shock environments of SRM firings 37) , assessments of attenuation of radio frequency signal due to the SRM plume 38,39) , and so on. In order to improve the reliability of SRMs, it is important to establish the accuracy of numerical simulation with progress of model refinement of each physical phenomenon checking with real firing results.…”

Properties of steady‐state solutions for a simulated solid rocket motor

“…Stability of solid rocket motors and combustion chamber flow-fields have been studied by many authors. Among the recent analytical and numerical works one can mention Balachandar et al (2001), García-Schäfer andLiňán (2001), Apte and Yang (2002), Flandro and Majdalani (2003), Kurdyumov (2006), Flandro et al (2007, Shimada et al (2008) and Massa (2009). More references can be found in these papers and in the review of Culick and Yang (1992).…”
