Dynamic cavitation characteristics of the DME blended fuel and enhanced atomization performance using cavity–orifice injector
DME has been regarded as a promising derivative from natural gas and used in engine systems to reduce emissions. The high vapor pressure of DME leads to intensified cavitation patterns, affecting the atomization and mixing performance of the DME blended fuel. In the present paper, the DME cavitation...

The high vapor pressure of DME leads to intensified cavitation patterns, affecting the atomization and mixing performance of the DME blended fuel. In the present paper, the DME cavitation generation mechanism induced by needle motion was investigated using the dynamic grid. Highly transient cavitation evolution and interacting vortices were observed in the initial stage of the needle opening, attributed to throttling, flow redirection, and vortical effects. The cavity–orifice injector was proposed to achieve the trade-off between the fuel delivery and acceptable atomization performance. Potentials of cavity–orifice in enhancing spray performance of DME blended fuel were evaluated by an integrated spray model combined with the improved momentum coupling method. The cavity–orifice injector with an appropriate cavity position provides better spray characteristics than conventional injectors by altering cavitation distribution. The present study offers potential options to improve fuel atomization performance of DME blended fuel through appropriate nozzle geometry design. | ||

dynamic cavitation characteristics of the dme blended fuel and enhanced atomization performance using cavity–orifice injector |
| title_auth |
Dynamic cavitation characteristics of the DME blended fuel and enhanced atomization performance using cavity–orifice injector |
| abstract |
DME has been regarded as a promising derivative from natural gas and used in engine systems to reduce emissions. The high vapor pressure of DME leads to intensified cavitation patterns, affecting the atomization and mixing performance of the DME blended fuel. In the present paper, the DME cavitation generation mechanism induced by needle motion was investigated using the dynamic grid. Highly transient cavitation evolution and interacting vortices were observed in the initial stage of the needle opening, attributed to throttling, flow redirection, and vortical effects. The cavity–orifice injector was proposed to achieve the trade-off between the fuel delivery and acceptable atomization performance. Potentials of cavity–orifice in enhancing spray performance of DME blended fuel were evaluated by an integrated spray model combined with the improved momentum coupling method. The cavity–orifice injector with an appropriate cavity position provides better spray characteristics than conventional injectors by altering cavitation distribution. The present study offers potential options to improve fuel atomization performance of DME blended fuel through appropriate nozzle geometry design. |
