CHEMISTRY-TURBULENCE COUPLING IN A MODEL OF INHOMOGENOUSLY PREMIXED COMBUSTION
TASK Quarterly, 2003 Results of work on an extension of the turbulent flame speed model used for a mathematical description of partially premixed combustion are presented. The approach is based on the concept of internal coupling between the turbulence of the mixed fuel and

Study on combustion performances of partially premixed flame in a micro-combustor with cavity
Case Studies in Thermal EngineeringCombustion characteristics of a partially premixed flame in a micro-combustor with a wall cavity were studied numerically under various conditions (primary air coefficient, α = 0.35, 0.5, and 0.65).

Simulation of turbulent non-premixed and partially premixed flames using a look-up table
Journal of Thermal Science and Technology, 2014 In this paper, we present a simple combustion simulation technique based on a look-up table approach. In the proposed technique, a flow solver extracts the solutions of the ordinary differential equations (ODEs) of the chemical equations from the look-up

Two recent developments in numerical simulation of premixed and partially premixed turbulent flames
Comptes Rendus. Mécanique, 2006 A subgrid scale closure for Large Eddy Simulation of premixed turbulent combustion (FSD-PDF) is proposed. It combines the Flame Surface Density (FSD) approach with a presumed Probability Density Function (PDF) of the progress variable that is used in flamelet chemistry tabulation.

Combustion mechanism of propane-air swirling premixed flame near lean flammability limit
Journal of Thermal Science and TechnologyThis study investigated a premixed propane-air flame in a partially tapered swirl burner. Experimentally, we found that a flame resembling a morning glory flower formed at an equivalence ratio near the lean flammability limit.
