Verification and Validation of Rocket Stability Integral Transformations

Abstract

This paper presents affirmation of the work we have performed to improve upon current combustion instability predictive capabilities. Recently, the ten stability integrals presented

Analytical Models for Hybrid Rockets

“…Attempts at predicting these instabilities have invariably pointed to the importance of providing accurate assessments of rocket core flow detail [30][31][32][33][34]. Attempts at predicting these instabilities have invariably pointed to the importance of providing accurate assessments of rocket core flow detail [30][31][32][33][34].…”

Hydrodynamic Stability Analysis of Solid Rocket Motors with Arbitrary Grain Design

“…Through the present work, the analytic models developed by Abu-Irshaid, Majdalani and Casalis, 5 Bhatia et al, 6 and Chedevergne et al [1][2][3][4] will be implemented in an improved combustion instability framework originating from the efforts of Flandro et al 7,8 The need to incorporate hydrodynamic instability waves in combustion instability computations has been recently emphasized by Casalis and co-workers, particularly by Chedevergne et al, [1][2][3][4] Griffond and Casalis, 9,10 Griffond, 11 Féraille and Casalis, 12 and others. The importance of accounting for unsteady vorticity in general has been emphasized by Fischbach et al, [13][14][15][16] Flandro et al, 7,8 Flandro and Majdalani, 17 Majdalani et al, [18][19][20][21][22][23][24][25][26][27][28][29] Balachandar et al, 30 Wasistho et al, 31 and others. [32][33][34] Our chief purpose will be to extend and implement their techniques in a general 3D capable linear stability tool that has been under development by French et al [35][36][37]…”
