Fundamental Study of Three Dimensional Two Phase Flow in Combustion Systems
Abstract
Combustion systems involve the complex interaction between several fundamental phenomena. In this investigation, the basic science underlying the interactions between the two-phase flow, fluid dynamics, and chemical kinetics have been investigated. The studies have required the development of new diagnostic systems and significant progress has been made in the following areas:- The development of a technique for making accurate dropsize measurements in dense sprays. The application of this technique to an F101 air blast atomizer. The use of LDA for the precise characterization of swirl from the F101 swirler. The development of shear stress mathematical models for non-isotropic turbulence. The application of this model to the F101 swirler. The development of a mercury vapour pulse tracer for residence time distribution measurement in combustors. The development of a mathematical modelling technique whereby the residence time distribution can be computed. Closing of the gap between stirred reactor models and finite difference models of combustion systems. Proposal of a new fundamental approach to the problem of simultaneous mixing and reaction using a quantitiative coalescene/dispersion eddy concept which has the potential to represent all the high order correlations of the interaction. Originator- supplied keywords include: Combustion modelling; Droplet sizing, Swirling flow, Algebraic stress modelling.
