Numerical prediction of flow and heat transfer on lubricant supplying and scavenging flow path of an aero-engine lubrication system
This paper presents a numerical model of internal flows in a lubricant supplying and scavenging flow pathof an aero-engine lubrication system. The numerical model was built in the General Analysis Software of Aero-engineLubrication System, GASLS, developed by Northwestern Polytechnical University. The lubricant flow flux, pressureand temperature distribution at steady state were calculated. GASLS is a general purpose computer program employeda 1-D steady state network algorithm for analyzing flowrates, pressures and temperatures in a complex flow network.All kinds of aero-engine lubrication systems can be divided into finite correlative typical elements and nodes fromwhich the calculation network be developed in GASLS. Special emphasis is on how to use combin ed elements whichis a type of typical elements to replace some complex components like bearing bores, accessory gearboxes or heatexchangers. This method can reduce network complexity and improve calculation efficiency. Final computationalresults show good agreement with experimental data.
