Abstract

The analytical solution of the mixing efficiency of the lobed mixer

in relation to that of the splitter mixer in the same cross-section area of outlet

was proposed by using the circular streamlines model

the planar diffusion flame model and the slender-body approach etc.

based on thoroughly study of the mixing mechanism of the lobed mixer.Then

the mixing efficiency of a practical turbo-fan engine lobed mixer was calculated in four flying cases.The results show that this analytical solution method is reliable and also applicable to the practical engineering calculation.
