abstract

Porous medium (PM) has potential advantage to enhance evaporation of droplets in liquid-fuel burners, low emissions and minimize instabilities of combustion. This paper represents the numerical study of liquid-fuel injection, evaporation, and combustion inside constant-volume chemically inert PM. It stabilizes lean combustion and decreases emissions. Three-dimensional numerical results were obtained based on a modified KIVA-3V code. Diesel fuel is directly injected into chamber for two cases, free volume and PM reactor. With high initial temperature, fast evaporation and self-ignited occur. The results for specified conditions were compared with experimental data in literature. Effects of injection on mixture formation was investigated. Distribution of diesel vapor, fluid and solid temperature of PM in a cutting plane, were shown. Diagram of diesel vapor, CO, NO, Soot, solid and fluid temperature versus time for different mass of injected fuel, were presented. Also, results of diesel vapor, pressure and temperature in free volume and PM reactor have compared. The results show considerable reduction in maximum pressure and temperature, carbon monoxide, nitrogen monoxide and soot formation in PM reactor in comparison with free volume.
