||The effect of obstrucions on combustion in flammable vapour clouds - steady state combustion
||United Kingdom Atomic Energy Authority, Wigshaw Lane, Culcheth, Warrington WA3 4NE, United Kingdom, 1990. 48p. Illus. 13 ref.
||In this report, the combustion of flammable mixtures in the presence of obstacles is considered in order to quantify the dependence of overpressures on the amount of obstruction and the mixture properties. Similarity solutions to a one-dimensional combustion model are derived which enable steady-state flame speeds and overpressures to be calculated for a specified burning velocity. Simple models are presented which relate this burning velocity to geometric features of the flow field. Comparisons with experimental data support the existence of a threshold for the amount of obstruction above which flame speeds and overpressures are substantial, although no precise relationship has been identified.
