Ignition and Flame Propagation in Sprays.
Abstract
An experimental and numerical analysis of ignition and flame propagation in sprays is done. A unique multi-orifice impulsed spray generator is designed and developed. This spray generator is capable of producing arrays of droplets, with controllable droplet size and spacings. Radiation effect on the droplet evaporation in spray, upstream of the flame front is studied through analytical modeling. An extensive numerical optimization study has been performed to compare the efficiency of several explicit and implicit schemes, and a numerical code has been developed to study a stabilized laminar flame in two-phase mixtures. A hybrid Eulerian-Lagrangian scheme has been developed to solve the gas and liquid phase equations.
