Large 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 ...

A fractal model for large eddy simulation of turbulent flow

A new class of subgrid closures for large eddy simulation (LES) of turbulence is developed, based on the construction of synthetic, fractal subgrid-scale fields. The relevant mathematical tool, fractal interpolation, allows to interpolate the resolved velocity with fields that have fluctuations down to much smaller scales and to compute the required stresses explicitly. In one dimension, the ap...

Large-eddy Simulation of a Particle- Laden Turbulent Channel Flow

Large-eddy simulations of a vertical turbulent channel flow with 420,000 solid particles are performed in order to get insight into fundamental aspects of a riser flow. The question is addressed whether collisions between particles are important for the flow statistics. The turbulent channel flow corresponds to a particle volume fraction of 0.013 and a mass load ratio of 18, values that are rel...
