In this study, it is focused on spray characteristics of Dimethyl ether (DME) injected into low temperature or pressure ambient. Quiescent ambient made in a constant volume chamber, and shadowgraph method or laser scattered method was conducted to visualize a shape of DME spray or liquid phase DME. Penetration of DME spray and liquid phase were measured with acquired images of DME spray and scattered lights. The results obtained in this experiment describe below. As injected DME sprays in a low pressure ambient, flash boiling phenomena occurs. As an ambient density increases, dispersion angle of DME spray with flash boiling decreases. As DME spray develops without flash boiling, the spray dispersion angle increases with the increases in the ambient density.
