Studies of Multi-Component Droplet Groups with Wall, Surface Tension, and Non-Ideal Influences

abstractcts - 0089444 h。这个项目包括一组多组分液滴阵列的实验和数值模拟研究。研究了含乙醇添加剂的烷烃燃料。乙醇的加入引入了未掺杂的烷烃燃料中不存在的过程，这些是研究的重点。它们包括液滴中的非理想液体效应、液滴表面的马兰戈尼力、添加剂向气相的优先扩散以及实际气体对热力学性质的影响。该研究包括孤立液滴、液滴阵列和液滴组以及液滴与热壁和冷壁的相互作用。研究结果与燃油喷射发动机中化石燃料的使用和污染物的控制有关。

AbstractCTS-0089444H. Dwyner, U of Cal DavisThis project consists of a set of experimental and numerical modeling studies of multicomponent arrays of droplets. Alkane fuels containing ethanol additive are studied. The addition of ethanol introduces processes not present in undoped alkane fuels, and these are the focus of the study. They include nonideal liquid effects in the droplet, Marangoni forces along the droplet surface, preferential diffusion of the additive into the gas phase, and real-gas influences on thermodynamic properties. The study includes isolated droplets, droplets in arrays and groups, and interactions of droplets with hot and cold walls. The results are relevant to the use of fossil fuels in fuel-injected engines and the control of pollutants.
