Numerical investigation of the effect of ambient turbulence on pressure swirl spray characteristics
in International Journal of Multiphase Flow
Description | Good progress has been made in generating new global correlations to predict the lift-off hight and blow-off characteristics of turbulent jet flames, flares and fires. These include methane and propane subsonic vertical jet-flames, both with and without diluent air. In addition, collaborative work with third parties has lead to the gathering of vital and new experimental data for the validation of computational predictions based on solution of the RANS equations for the above problems, in particular when such events are subjected to a cross flow. Important numerical predictions have been obtained with respect to modelling the effect of ambient turbulence on pressure swirl spray characteristics associated with engine combustion and efficiency, and compared with complementary experimental results. |
Exploitation Route | The correlations that have been formulated will be of considerable interest to oil and gas companies worldwide and any organisations concerned with health and safety issues apropos fire and explosion hazards. The computational studies undertaken are also of direct relevance to fracking and emissions/pollutants arising from flaring. As to the modelling of the interaction between ambient turbulence and sprays, this will be of particular interest to worldwide petrol and diesel engine manufacturers apropos efficiency and pollutant mitigation. |
