Gas Turbine Secondary Air Systems Modeling
Volume 6B: Heat Transfer — General Interest/Additive Manufacturing Impacts on Heat Transfer; Internal Air Systems; Internal Cooling, 2022Abstract Modern gas turbine engine designers are challenged with aggressive power, cycle efficiency and operational life requirements. Those targets are directly related with turbine inlet temperature, material selection and design choices.

D6 Secondary Air System In this Chapter we show how the very complex secondary air system in a modern gas turbine may be greatly simplified and integrated into a cycle model without compromising the quality of overall performance results. Calculation examples from single and multi-stage turbines are given which describe in detail how to account for ...

Secondary Air System Component Modeling for Engine Performance Simulations
Journal of Engineering for Gas Turbines and Power, 2008Abstract This paper describes the modeling of typical secondary air system elements such as rotating orifices, seals, and flow passages with heat and work transfer from the surrounding surfaces. The modeling is carried out in an object-oriented simulation environment that allows the creation of different configurations in a simple and ...

Automated Hex Meshing for Turbomachinery Secondary Air System
International Meshing Roundtable Conference, 2013In this paper, we present a novel process of creating hexahedral meshes for the turbomachinery secondary air system. The meshing process is automated from the geometry import to the mesh setup and requires minimum human interventions. The core of the process is a hexahedral meshing algorithm with a boundary layer mesh automatically created.

Separation of Particles in the Secondary Air System of Gas Turbines
Volume 1: Aircraft Engine; Ceramics; Coal, Biomass and Alternative Fuels; Wind Turbine Technology, 2011Particles contaminating the secondary air system of land based gas turbines or aero-engines can cause serious problems in various engine components, particularly in the cooling system. The capability of the pre-swirl system in separating particles will be described in this paper.
