| dcterms.abstract | A computational fluid dynamics (CFD)-based study using large-eddy simulation (LES) and the flamelet-progress variable (FPV) approach for turbulence-combustion interaction has been undertaken to investigate the combustion that takes place under supersonic flow conditions. The target application is the propulsive system associated with dual-mode scramjet, which has been recognized as the most promising air-breathing system for hypersonic flight. In addition to the standard practice of using mixture fraction and its dissipation rate as independent variables of the look-up table in the flamelet procedure for non-premixed flames, pressure has been added to enable the inclusion of its effects on chemical reactions under high speed conditions. An improved method of generating the flamelet library that allows new interpolations based on the three branches of the reaction curve (S-Curve) in non-premixed combustion has been proposed during the course of the present work. Solutions of supersonic combustion in three different configurations have been used to assess the accuracy of the various proposed improvements and investigate fundamental physics of dual-mode scramjets. | |
