Aspects of computer simulation of liquid-fuelled combustors

Open publisher page 551 citations

Abstract

An existing 'discrete droplet' model of liquid sprays has been extended to include a stochastic representation of turbulent dispersion effects. Applications to simple test cases, including the dispersion of single particles, produce reasonable agreement. However, two further applications involving volatile and combusting sprays respectively show that the turbulent dispersion effects are small in comparison to those due to uncertainties about the initial conditions of the spray. 31 refs.
