Notizen:
The combustion flow of a sudden-expansioin dump combustor with injecting side-inlet is analysed using the SIMPLE-C algorithm and the Jones-Launder k-∊ two-equation turbulence model. The transport properties of velocity, turbulence kinetic energy, temperature and combustion efficiency as a function of the injected mass fraction and the number of side-inlet nozzles are solved in this paper. The axial velocities of the sudden-expansion dump combustor without injected side-inlet flow are solved first and found to be in good agreement with the experimental data of Moon and Rudinger. For a fixed value of the side-inlet number the wall temperature and combustion efficiency of the dump combustor are decreased when the injected mass fraction is increased. For a fixed value of the injected mass fraction the wall temperature and combustion efficiency are decreased when the number of side-inlet nozzles is increased.
