LES modeling for lifted turbulent jet flames
The LES method is an attractive approach for the simulation of turbulent jet flames. In this method, the effects of large scale structures controlling the mixing process are resolved while small-scale effects such as the leading-edge flames involved in the flame base dynamics are accounted for by the subgrid-scale models. The LES approach is examined in this study with a particular emphasis on ...
متن کاملTemperature response of turbulent premixed flames to inlet velocity oscillations
Flame–turbulence interactions are at the heart of modern combustion research as they have a major influence on efficiency, stability of operation and pollutant emissions. The problem remains a formidable challenge, and predictive modelling and the implementation of active control measures both rely on further fundamental measurements. Model burners with simple geometry offer an opportunity for ...
متن کاملUnsteady Flamelet Modeling of Turbulent Hydrogen-air Diffusion Flames
The unsteady flamelet model is applied in numerical simulations of a steady, turbulent, nitrogen-diluted hydrogen-air diffusion flame. An unsteady flamelet is solved interactively with a CFD solver for the turbulent flow and the mixture fraction field. Transient effects occurring in steady jet diffusion flames are discussed in terms of the relevant timescales. It is shown that radiation can be ...
متن کاملModeling of Moderately Swirling Turbulent Non-premixed Flames
Even if the goal of reducing NOx emissions pushes towards the use of premixed combustion, moderately swirling turbulent non-premixed flames are still widely employed in both industrial furnaces and gas turbines, because of their stable and safe behaviour in a wide range of fuels and operating conditions. Computational Fluid Dynamics (CFD) has become in recent years a key tool for the design of ...
متن کاملModeling Turbulent Nuclear Flames in Type Ia Supernovae
In this paper we present the application of the so-called level set method as a ame model in simulations of Type Ia supernovae. After giving a short introduction and motivation for our choice, we discuss two diierent implementations and preliminary results of test calculations and SN Ia explosions.
