    Notes: 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.

    Diffusion flame analysis of an afterburner as a function of the air-fuel ratio (1990)
    Chichester : Wiley-Blackwell

    Notes: The diffusion flame of an afterburner as a function of the air-fuel ratio is analysed by employing the SIMPLE-C algorithm and the turbulence κ-κ model. In the present analysis, better combustion efficiency of an afterburner with a slightly fuel-lean mixture is shown. The velocity, fuel mass fraction, temperature and combustion efficiency distributions of reacting flow in an afterburner with two V-gutter flameholders as a function of the air-fuel ratio are also discussed and compared. The calculated results in the present analysis can be applied to the fundamental study of reacting flow in an afterburner.
