Combustion Coupled Flow Dynamics in Solid Rocket Motors

摘要: Abstract : The literature on pulse detonation engine (PDE) and rocket (PDRE) modeling experiments has been reviewed with the goal of determining characteristic operational time length scales, key parameter ranges approaches used for evaluating device efficiency. roles igniter power level, duration location initiation a assessed gaseous mixture systems those based multiphase sprays. A secondary phase project is focused completion technical papers describing nonlinear dynamics unstable solid motors. Results from asymptotic analysis computation predict acoustic disturbances, role they play in generation vorticity thermal gradients, as well further evolution these disturbances. are valid pressure disturbances large 10% base value, relative to linear stability theories, where must be factor 100 smaller.
