Figure 3
Measured fuel mass as a function of the radial position at three different axial positions. In this figure, the fuel mass was measured in the main body of the spray at time t = 0.27 ms. The curves are Gaussian fits to the data. The inset shows the calculated volume fraction at distances of 1 and 6 mm for the leading edge (upper panel) and main body (lower panel) of the spray. A volume fraction equal to unity implies the density of pure liquid fuel. The data shown were measured at 500 bar injection pressure and 300 µs injection duration using SF6 as the chamber gas. |
