Numerical Investigation of Aero Engine Afterburner Fuel Manifold

Abstract:

In this paper, Method of CFD is used to simulate afterburner fuel manifold for aero engine, and investigate the relationship between the boundary layer of nozzle hole and mass flow. At the same time the numerical simulation of permitted maximum and minimum of nozzle hole was carried out and mass flow for calculation was also compared with the design value. The calculation results show the effect of machining quality of nozzle holes on mass flow of afterburner fuel manifold, for which the diameter of nozzle hole is so small that the effects of machining precision and boundary layer thickness on mass flow is very large. Therefore the jet fuel must be machined according to tolerance level I so as to ensure that the mass flow meets the design requirements. Investigation of boundary layer of small hole shows that only the boundary layer factors are fully considered, the numerical calculation accuracy may be enhanced.
