Abstract:
The research on mixture characteristic of two same liquid sheets generated after the impinging of splash platelet injector is conducted. The effect of expanding angle (β) of liquid sheets on mixing efficiency (Em) is discussed. In the process of investigation, the mathematical models of the mass flux distribution generated by single like liquid sheets impinging are founded based on analyzing and revising the mathematical models of mass flux distribution of two cylindrical jets impinging. The comparison result indicates that the relative deviation between suimulation calculation Em value and experimental value is in the range of -0.86% to 12.9%. The research results show that Em increases with the increase of β when β is less than 60°， but the variation law of Em along with the expanding angle is disordered when the angle is in the range of 60°-90°.
