An Experimental Study on DME Spray Characteristics and Evaporation Processes in a High Pressure Chamber 2001-01-3635

In this study, the spray characteristics and evaporating processes of DME fuel were investigated using the SCHLIEREN optical system and single-hole injectors in a constant volume chamber at room temperature. The photographs taken at different chamber pressures, injection pressures, orifice diameters and injection quantities were compared and analyzed. The results show that DME spray has a slower penetrating speed, wider spray angle, and much quicker evaporating processes than the diesel spray.
