Abstract

This paper attempts to research on a dual orifice centrifugal nozzle of a certain aero-engine using CFD method to numerically simulate the interior flow, which will provide reference for design. The computing models for the primary fuel line and the secondary fuel line of the nozzle are built separately. The a reasonable computing domain is determined, and the geometry model is built using 3-D CAD software UG, and the grid of high quality is meshed by means of splitting volumes. With the boundary conditions and computing parameters determined according to data from experiments and references, the interior flow in the primary fuel line and the secondary fuel line of the nozzle is simulated using VOF model, and the velocity, pressure, phase volume fraction and spray cone angle are obtained for the primary and the secondary fuel line working separately. A 2-D axis-symmetrical model for the two circuits working simultaneously is created, with the result from the calculation of 3-D model as the boundary conditions, to give the spray pattern when working together for the primary and the secondary fuel line at the outlet of the nozzle. The comparisons between the numerical simulation results and the experiment data showed that the computing models comply with the nozzle working conditions.
