Error analysis of large-eddy simulation of the turbulent non-premixed sydney bluff-body flame
A computational error analysis is applied to the large-eddy simulation of the turbulent non-premixed Sydney bluff-body flame, where the error is defined with respect to experimental data. The errorlandscape approach is extended to heterogeneous compressible turbulence, which is coupled to combustion as described by a flamelet model. The Smagorinsky model formulation is used to model the unknown...
متن کاملNear-Blowoff Dynamics of a Bluff-Body Stabilized Flame
This paper describes an experimental investigation of the dynamics of a near-blowoff, bluff-body stabilized flame. This work is motivated by a number of prior observations showing that near-blowoff flames exhibit enhanced unsteadiness. Laser sheet imaging studies and particle image velocimetry velocity field measurements show that the transient dynamics of these flames occur in two distinct sta...
متن کاملLarge Eddy Simulation of an Oscillating Flame in Turbulent Flow around a Bluff Body
The present research aims at providing a reliable model for the simulation of oscillating flames which are often discovered in industrial gas turbine combustors operating at lean premixed conditions. The paper presents a Large Eddy Simulation of an oscillating bluff-body stabilised flame with a probability density function model of the subfilter scale interaction. The results show good overall ...
متن کاملLarge-eddy simulation of a bluff-body-stabilized non-premixed flame using a recursive filter-refinement procedure
A large-eddy simulation (LES) of a bluff-body-stabilized flame has been carried out using a new strategy for LES grid generation. The recursive filter-refinement procedure (RFRP) has been used to generate optimized clustering for variable density combustion simulations. A methane–hydrogen fuel-based bluff-body-stabilized experimental configuration has been simulated using state-of-the-art LES a...
