THE EFFECTS OF ORGAN PIPE OSCILLATIONS ON FLAME PROPAGATION IN TUBES AND SAFOM AS A FLAME ARRESTER IN AIRPLANE VENT SYSTEMS.

Abstract

The paper describes a program to investigate the nature of flame propagation in a duct system of variable geometry, particularly the effect of acoustical disturbances; and to evaluate SAFOM as an arrester in ducts, and establish criteria for its use. Tests show that fuel mixture ratio, organ-pipe oscillation, and system configuration are involved in the flame quenching capability of SAFOM and a combination of SAFOM and metal screens. Zones where arrest cannot occur are detected, and the arrester combination of SAFOM and metal screen is recommended for quiescent conditions. However, if the combustible mixture is flowing, the arrester (SAFOM and/or screens) acts as a flame-holder until failure occurs. (Author)
