摘要: An algorithm based on the Relaxation Redistribution Method (RRM) is proposed for constructing Slow Invariant Manifold (SIM) of a chosen dimension to cover large fraction admissible composition space that includes equilibrium and initial states. The manifold boundaries are determined with help Rate Controlled Constrained Equilibrium method, which also provides guess SIM. latter iteratively refined until convergence converged tabulated. A criterion departure from invariance find region over reduced description valid. global realization RRM applied constant pressure auto-ignition adiabatic premixed laminar flames hydrogen-air mixtures.
