| 초록 |
Characteristics of transient evaporting diesel sprays were investigated from LIEF data acquired under engine-like conditions (15 ㎏/㎥ and 800/1000 K ambient) with variation of peak injection pressures(60, 90 and 150MPa) and nozzle hole sizes(0.14, 0.15 and 0.2 ㎜). The spray penetration rate was found to be in good agreement with the Naber-Siebers model. The entrained air mass was found to also agree with the model results. An overall mean equivalence ratio profile was Gaussian(1.2 at the peak and 0.1 full width half maximum), but a progressive trend was observed with respect to the non-dimensional downstream distance. |
