Book Description

A fundamental approach to combustor modelling is being extended by the coupling of combustor flow fields and fuel droplet trajectories. The iterative procedures, which have been applied to a gas turbine, evaluate reacting flow fields and indicate the conditions under which fuel is able to escape incompletely evaporated from the burner. Important advances have also been made in the application of a valid turbulence model to the calculation of flow fields in non-isotropic swirling flows. This has important implications for combustor designing for a wide range of systems including gas turbines and ramjets. The development of a non-intrusive and rapid method for residence time distribution measurement has progressed to the point of application to a gas turbine combustor. This involves the optical detection of an electrically generated pulse of mercury vapour and can give residence times in real time. (Author).
