On the Structure and Morphology of Turbulent Premixed Flames

  • R. Borghi

Abstract

Turbulent combustion occurs in a majority of industrial devices. Many prediction methods have been proposed in recent years, and at the same time much experimental investigation has been performed. However, the physical structure of turbulent flames cannot be regarded as completely understood at present due to the complexity of the relevant experimentation.

This study aims at a synthesis between experimental findings and theoretical reasonings concerning the problem. A brief survey of previous discussions is presented first, with emphasis on three points around which controversy has been concentrated. The morphology of turbulent premixed flames in different conditions is described following a theoretical point of view; the presentation here synthesizes the discussions of earlier workers from different countries and different periods. The result is a comprehensive classification of turbulent premixed flames. The theoretical description is then compared with available experimental observations of the detailed structure of turbulent flames. Good agreement is achieved; however, experiments are very few and more research is required in this direction.
