Joint effect of input asymmetrical velocity profile and initial turbulence intensity on hydraulics of a separated diffuser of GTE combustion chamber

Abstract

This paper presents the regularities of effect of the input asymmetry of the velocity profile on the flow structure in a separated diffuser of the GTE annular combustion chamber. These regularities allow predicting the integral value of hydraulic resistance. We experimentally identified a kind of dependence between the hydraulic losses and Reynolds number in the case of asymmetric velocity profile in a prediffuser assessing the growth of pressure losses. Some updated dependencies are proposed that take into account the joint effect of the input parameters of the working fluid on the integral characteristics of its effectiveness.
