摘要: Moderate or intense low-oxygen dilution (MILD) combustion is a promising concept to reduce emissions and increase efficiency. It requires high levels of preheating reactants, which realized by mixing reactants with products. In order extend the application areas MILD combustion, adequate computational models must be developed. this study, one candidate models, flamelet generated manifolds (FGM), has been assessed in terms applicability combustion. Based on results assessment, novel multistage (MuSt) FGM method The need for developing such mainly stems from existence different stages regime, cannot represented single progress variable. MuSt-FGM approach, each stage modeled using variable, without increasing dimension lookup table. approach tested conducting priori simulating both 1D laminar 2D turbulent flames. Proving successful all three tests, emerges as tool modeling not only but also other systems where characterized stages.
