| 초록 |
The application of Dimethyl Ether(DME) as an alternative fuel is recently studied. In this paper, the characteristics of DME spray were investigated in a constant-volume vessel at 1~4 MPa and 900K. To obtain this condition, a mixture composed of C₂H₂, O₂ and N₂ had burned in the constant-volume vessel as a preliminary stages. Images of DME spray were taken with using a Mie scattering and Schlieren method under a evaporating condition and a non-evaporating condition. Comparing with a non-evaporating condition, spray penetrations was decreased and spray angle was increased in a evaporating condition. |
