A Unified Description of Flame Topologies at Different Turbulent Combustion Regimes Using Computational Singular Perturbation
  Identifying turbulent flame topologies for unambiguous deter-mination of key flame quantities is a challenging task for high Karlovitz number conditions in which different scalar variable sexhibit drastically distinct characteristics. The present study explores a unified way to characterize the flame topologies and its important observable quantities by the identification of representative dynamical features using the computationalsingular perturbation (CSP) technique. Various algorithmic toolsof CSP are applied on DNS datasets of turbulent premixed hydrogen/air flames at different combustion regimes and the results are compared with conventional flame analysis tools.
