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 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...
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 turbulent non-premixed propane-air reacting flame in a cylindrical combustor
Large Eddy Simulation (LES) is applied to investigate the turbulent non-premixed combustion flow, including species concentrations and temperature, in a cylindrical combustor. Gaseous propane (C3H8) is injected through a circular nozzle which is attached at the centre of the combustor inlet. Preheated air with a temperature of 773K is supplied through the annulus surrounding of this fuel nozzle...
متن کاملPlanar Laser-Induced Fluorescence in a Turbulent Premixed Flame to analyze Large Eddy Simulation Models
Large eddy simulations (LES), where the large-scale motions are explicitly computed, is a promising tool for numerical simulations of reactive flows which generally exhibit large coherent structures. Nevertheless, subgrid-scale models have to be developed to describe the effects of the smaller flow motions not resolved in the simulation. An experimental method is presented for validation and de...
