Abstract:

An investigation was made of the interaction between multiple dilution jets discharging from a common annulus into hot combustion products. Gas concentrations, mean and fluctuating gas temperatures using compensated fine wire thermocouples have been measured throughout the mixing region for three dilution jet flow rates. A parallel theoretical study of the same flows has been conducted using the Rolls-Royce PACE computer code this is a finite difference program employing K - epsilon turbulence sub-model. The output from this program has proved useful in visualizing the flow and interpreting the experimental data. Attention is drawn to the care needed when comparing various types of experimental information and apparently similar parameters output from computer codes on a mass flow weighted basis.
