To determine the effect of pressure P, and equivalence ratio _ on soot concentration at the chamber exit. To determine the axial distribution of soot concentration at different P and _. To determine the radial distribution of soot concentration. To compare measured data with predictive models.RESEARCH PROGRAMMEThe programme provides experimental data for validation of models predicting soot emissions from high-pressure combustion systems such as diesel engines. Stable combustion of a liquid-fuel spray in air at pressures up to 3.0 MPa and at input equivalence ratios of 0.8 to 1.2 has been achieved extending the operating range of earlier work (below 1.0 MPa). The fuel spray is delivered along, or at an angle to, the chamber axis into air with uniform flow or swirling about this axis.Samples of combustion products from the exhaust and different locations inside the combustion chamber are analysed for gaseous species and soot concentrations and particle size distributions of the soot agglomerates measured. the increase in magnitude and subsequent reduction through oxidation of the soot concentration along the flame will be quantified for different conditions. To date exhaust samples have been analysed for the full operating range.
