| 摘 要： | 燃油喷射瞬态雾化、蒸发及与空气混合过程的研究，是目前国内外柴油机燃烧与净化研究的前沿课题。利用激光技术与计算机图象处理技术，首次提出了对燃油喷雾蒸发过程中，气液两相的油滴密度与燃气浓度的三维分布，进行动态非接触同步定量测量的理论，通过自建的测试系统，给出了部分试验结果，为柴油机燃烧性能及排污的进一步改善提供了一定的理论依据。

| Abstract: | The investigation of transient spray, evaporation and mixture with air of fuel is the frontier task of the studying of the diesel engine combustion and purification. The theory of non dynamic contact and sync measurement of the distribution of the fuel droplet density of two phrase of vapour and liquid and the gas, three dimensional concentration is pointed out in the process of fuel spray and evaporation by using laser and computer image processing technique. The partial testing result provided the theoretical foundation for improving the combustion performance and exhaust of the diesel engine. |
