淡水与微咸水入渗特性对比分析（Infiltration Characteristic Contrast Analysis of Fresh Water and Saline Water）
微咸水 淡水 间歇入渗 连续入渗
2010/12/29
为了研究淡水与微咸水连续和间歇入渗特性的差异，采用矿化度1.33g/L的淡水与矿化度3g/L的微咸水，在黏质土壤条件下进行了一维积水连续入渗及间歇入渗试验。研究结果表明，采用微咸水入渗可以改变土壤的结构特性，从而增大土壤的入渗能力；利用一维代数入渗模型对试验资料进行处理，结果表明模型可以比较精确地描述微咸水入渗过程；入渗水为淡水时，间歇入渗减渗，而入渗水为微咸水时，间歇入渗增渗；间歇入渗的循环...
高压涡旋喷油器喷雾撞壁机理研究（Spray Impingement Characteristic of GDI High-pressure Swirl Injector）
汽油缸内直喷 高压涡旋喷油器 喷雾撞壁 机理
2010/12/29
为了研究直喷式汽油机高压涡旋喷油器喷雾撞壁机理，测量了撞壁喷雾的高度、喷雾半径及喷雾远端速度，分析了不同喷射压力、环境背压、喷嘴到壁面的距离、壁面倾角等因素对撞壁喷雾的影响。随着喷射压力、喷嘴到壁面的距离及壁面倾角的增加，喷雾的贯穿距离增大；环境背压的增大导致喷雾的贯穿距离减小。较高的喷射压力和较低的环境背压增大了撞壁燃油与壁面的接触面积，在壁面上形成的薄膜加速了燃油的蒸发。由经验公式计算得到的撞...
