    Computations for a jet impinging obliquely on a flat surface (1991)

    Notes: A SIMPLE-C algorithm and Jones-Launder k-ε two-equation turbulence model are used to simulate a two-dimensional jet impinging obliquely on a flat surface. Both the continuity and momentum equations for the unsteady state are cast into suitable finite difference equations. The pressure, velocity, turbulent kinetic energy and turbulent energy dissipation rate distributions are solved and show good agreement with various experimental data. The calculations show that the flow field structure of the jet impinging obliquely on a flat surface is strongly affected by the oblique impingement angle. The maximum pressure zone of the obliquely impinging jet flow field moves towards the left as the oblique impingement angle is decreased.

    Diffusion flame analysis of an afterburner as a function of the air-fuel ratio (1990)
    Chichester : Wiley-Blackwell
    International Journal for Numerical Methods in Fluids 11 (1990), S. 303-316

    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.

    Theoretical investigation of combustion characteristics in ram-jet dump combustor with side-inlet (1992)
    Chichester : Wiley-Blackwell
    International Journal for Numerical Methods in Fluids 15 (1992), S. 1197-1212

    ISSN: 0271-2091
    Keywords: Combustion flow ; Combustor ; Side-inlet ; Numerical calculation ; SIMPLE-C algorithm ; Engineering ; Engineering General

    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.
