ABSTRACT Hydrogen chlorine (HCl) is an important combustion intermediate during plastic (municipal waste) and composite propellant (aerospace) combustion, but the understanding of its high‐temperature chemistry is still evolving. In this study, the pyrolysis of 0.5% HCl in Ar was investigated behind reflected shock waves in a shock tube at temperatures

Simulation of partially premixed turbulent flames
This work numerically investigates the turbulent partially premixed flames, which are ubiquitous in combustion powered devices. This combustion mode involves many physical complexities such as flame propagation in unevenly premixed mixture of fuel and oxidiser, turbulence/flame interaction in presence of mixture fraction gradients, triple flame ...

CHEMISTRY-TURBULENCE COUPLING IN A MODEL OF INHOMOGENOUSLY PREMIXED COMBUSTION
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
Combustion 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
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
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.
