- Abstract
At present, most of the researches on spray characteristics are focused on free injection cases. This paper researches the spray impingement phenomenon of CTL fuel in a visualization test system by high-speed photograph technology and discusses the influences of ambient pressure and wall distance on impingement process. The results show that the wall diffusion radius increases linearly, the entrainment height increases firstly and then keeps stable gradually and the velocity of spray tip decreases rapidly with CTL continuation injection. When the ambient pressure increases, impingement wall time delays and initial impingement radius increases, and it is the same situation with increasing wall distance. Simultaneously, increasing ambient pressure can reduce the spray diffusion radius and raise the entrainment height, while it displays an opposite trend with increasing wall distance. The contrast test results of spray wall-impingement for both of two fuels show that CTL fuel exhibits a slightly later spray impingement wall, a shorter spray diffusion radius and a thinner entrainment height than No.0 diesel. The research results have a certain reference value to guide the application of CTL in diesel engines.
