High mixing effectiveness lobed nozzles and mixing mechanisms被引量：3
《Science China(Technological Sciences)》2015年第7期1218-1233,共16页SHENG ZhiQiang CHEN ShiChun WU Zhe HUANG PeiLin 
supported by the Assembly Research Foundation of China
For a circular lobed nozzle with the exit plane displaced from the center body,adding a central plug at exit or replacing the nozzle with an alternating-lobe nozzle can improve the mixing effectiveness.In this study,n...
