Large Eddy Simulation of Bluff Body Stabilized Premixed Flame
- 44th AIAA Aerospace Sciences Meeting and Exhibit, AIAA
, 2006
"... This paper presents results of numerical simulations of cold and reactive flow behind a bluff body, in comparison with experimental data. The results of the non-reacting flow are found in good agreement with the experiments. For the reactive flow, two closures for the filtered scalar transport equat ..."

1 Influence of Turbulence-Chemistry Interaction in Blow-out Predictions of Bluff-Body Stabilized Flames
"... Large Eddy Simulations (LES) were performed to investigate the effect of turbulence – chemistry interaction on flame instability and flame-vortex interactions in bluff body stabilized premixed flames. A semi-global reduced kinetics mechanism and a skeletal mechanism were developed and implemented wi ..."

LARGE EDDY SIMULATION OF BLUFF-BODY STABILIZED FLAME BY USING FLAME SURFACE DENSITY APPROACH
"... Abstract. Despite significant advances in understanding and modelling of combustion-LES, LES of premixed combustion remains a challenging issue. This problem is more challenging when an incompressible formulation is used where the density coupling is weak, and an improper density coupling can lead t ..."

to unrealistic flame speeds and thickness. For this purpose the flame surface density approach is used along with an appropriate numerical technique. By incorporating the proper flame wrinkling model, the LES of Bluff-body stabilized premixed flame are carried out and numerical results are compared
THE ZIMONT TFC MODEL APPLIED TO PREMIXED BLUFF BODY STABILIZED COMBUSTION USING FOUR DIFFERENT RANS TURBULENCE MODELS
"... ABSTRACT The Volvo Aero Corp. (VAC) Triangular Bluff Body Stabilized Combustion rig VR-1 has been extensively researched both in terms of experiments and theoretical treatment. Previous CFD work has concentrated on Reynolds Averaged Navier-Stokes (RANS) models combined with the Level Set Flamelet L ..."

Alex Klusmeyer Prediction of Blow-Offs of Bluff Body Stabilized Flames Utilizing Close-Coupled Injection of Liquid Fuels
"... This paper describes the development of an empirical approach that attempts to predict blow-out of bluff body stabilized flames using global flow parameters in systems where liquid fuel injectors are located a short distance upstream of the wake. This approach was created on the hypothesis that fla ..."

Original Article Effects of a New Industrial Lifting Belt on Back Muscular Activity, Hand Force, and Body Stability during Symmetric Lifting
, 2005
"... Abstract: This work investigated how wearing a new design of back belt affects erector spinae activity, hand force, and body stability. The belt was first tested with static holding tasks and found to significantly decrease the back muscle activity. Actual lifting tasks were further carried out to t ..."

THE BLUFF BODY STABILIZED PREMIXED FLAME IN AN ACOUSTICALLY RESONATING TUBE: COMBUS- TION CFD AND MEASURED PRESSURE FIELD.
, 2009
"... The resulting limit cycle amplitude and frequency spectrum of a flame placed in a combustor of rectangular cross section is investigated. The partially premixed flame is stabilized on a bluff body placed in the upstream half of the combustor. The bluff body is an equilateral triangular wedge with on ..."
