Corrigendum to “Influence of m-xylene addition to Jet A-1 on spray structure, flow field and soot production in turbulent swirl-stabilized spray flames in a model combustor” [Combustion and Flame 219 (2020) 258–267]

A model gas turbine burner was employed to investigate spray flames established under globally lean, continuous, swirling conditions. Two types of fuel were used to generate liquid spray flames: palm biodiesel and Jet-A1. The main swirling air flow was preheated to 350 °C prior to mixing with airblast-atomized fuel droplets at atmospheric pressure. The global flame structure of flame and flow field were investigated at the fixed power output of 6 kW. Flame chemiluminescence imaging technique was employed to investigate the flame reaction zones, while particle imaging velocimetry (PIV) was utilized to measure the flow field within the combustor. The flow fields of both flames are almost identical despite some differences in the flame reaction zones.

The effect of high shear in the flow on the spray flame characteristic has been examined. The shear was provided using different swirl combination in the inner and outer swirlers in the double concentric swirl burner. The burner allowed independent control of swirl and combustion airflow in the inner and outer annulus of the burner. Particle Image Velocimetry (PIV) and Phase Doppler Particle Analyzer (PDPA) laser diagnostic tools have been used to obtain comprehensive data related to droplet size, velocity, number density, vorticity in the flow for dispersed phase, and flow and strain rate in the axial direction in the carrier phase. A commercially available twin fluid nozzle has been used in this study. Results have been obtained for a swirl combination of 65° in inner swirler and 30° in outer swirler (referred to as 65°/30°). The results are compared with a swirl combination of 50°/30°. The results show secondary break-up of the droplets with high shear that was not present with low shear in the flow. They also show new way to obtain smaller size of droplets from a spray. Smaller size of droplets allows one to easily control the size, shape, stability and structure of the spray flames.

Transfer Flow

The problem of combined free-forced convection and mass transfer flow over a vertical porous flat plate, in presence of heat generation and thermaldiffusion, is studied numerically. The non-linear partial differential equations and their boundary conditions, describing the problem under consideration, are transformed into a system of ordinary differential equations by using usual similarity transformations. This system is solved numerically by applying Nachtsheim-Swigert shooting iteration technique together with Runge-Kutta sixth order integration scheme. The effects of suction parameter, heat generation parameter and Soret number are examined on the flow field of a hydrogen-air mixture as a non-chemical reacting fluid pair. The analysis of the obtained results showed that the flow field is significantly influenced by these parameters.
