Available in PDF, EPUB and Kindle. Book excerpt: Analytical modelling and several experimental diagnostics were applied to an experimental flow in a two-dimensional subsonic windtunnel with a backward facing step and provision for injection of inerts and combustibles through the porous floor behind the step. The analytical techniques were based on a two equation modeling of turbulence with several variants of near wall models and numerical approaches. Conventional experimental techniques, where applicable in the cold flow, included hot film and pitot and anemometry. Laser - based diagnostics in the cold and hot flows for velocity and species concentration measurements (both mean and instantaneous) included laser velocimetry in two components and Rayleigh molecular scattering. Major findings in this complex turbulent flow with chemical reactions were a) there was a general agreement between analysis and experiment in cold flow both with and without wall injection, b) this agreement occurred at the the most detailed level of turbulent shear stress and mass transport, c) in hot flow there was acceptable agreement as to the gross features of the mean flow field, but some theoretical details, such as reattachment length, went counter to experimental results.

Available in PDF, EPUB and Kindle. Book excerpt: Using a flow visualization technique, stabilization and suppression of a nonpremixed methane flame behind a backward-facing step in a wind tunnel have been studied by impulsively injecting a gaseous fire-extinguishing agent into the airflow. As the mean air velocity was increased, two distinct flame stabilization and suppression regimes were observed: rim-attached wrinkled laminar flame and wake-stabilized turbulent flame. In the former, the flame detached immediately after agent arrival, while in the latter, the flame zone in the shear layer first became unstable, followed by the extinction of the flame in the recirculation zone.

Available in PDF, EPUB and Kindle. Book excerpt: Progress in Astronautics and Aeronautics—Volume 15: Heterogeneous Combustion focuses on the processes, reactions, methodologies, and techniques involved in heterogeneous combustion. The selection first offers information on the techniques for the study of combustion of beryllium and aluminum particles, study of quenched aluminum particle combustion, and spectroscopic investigation of metal combustion. Discussions focus on the combustion of metal particles in a hot oxidizing atmosphere, experimental apparatus and procedure, selected examples of residue observations, ignition of beryllium, and photographic study of particle combustion. The text then takes a look at the analytical developments, experimental observations in oxygen atmospheres, and experimental observations in carbon dioxide atmospheres of vapor-phase diffusion flames in the combustion of magnesium and aluminum. The publication ponders on the combustion of elemental boron with fluorine, combustion of pyrolytic boron nitride, characteristics of diborane flames, oxidation of diethyldiborane, and reaction of pentaborane and hydrazine and structure of the adduct. The selection is a dependable reference for readers interested in heterogeneous combustion.

Book excerpt: The extinction limits of a methane diffusion flame stabilized behind a backward-facing step in a small-scale wind tunnel were measured by injecting a fire-extinguishing agent (halon 1301) into the airflow. As the mean air velocity was increased, two distinct flame stabilization regimes were observed: rim-attached and wake-stabilized flames. For a fixed mean air velocity, the agent concentrations at extinction varied inversely with the agent injection period. As a result, the agent mass required to suppress the flame was nearly constant for a given air velocity, independent of the agent concentration and injection time. The critical agent mass increased with the mean air velocity.
