Abstract: The cover picture shows a laminar and a turbulent lean Bunsen flame using a mixture of CH4, O2 and N2 as fuel. Boron particles were injected in the centre of the flame in an inert carrier gas jet. The characteristic green light results from oxidation of the boron particles in the hot environment. In the laminar flame oxidation primarily takes place in the boundary region of the particle swarm, where temperature is high and oxygen is available. The core of the particle swarm is dominated by a red and a yellow light representing particles that do not yet undergo combustion. Due to a higher dispersion of the particles and oxygen in the turbulent flame, regions of burning and non-burning particles are not distinguishable. The flames were studied experimentally to provide validation data for Boron combustion models. Details are discussed in the article by Jan Veith and Michael Pfitzner on page 260 ff.
