Сопряженный теплогидравлический и термомеханический расчет двумерной модели газотурбинного двигателя

Abstract

The coupled thermal-hydraulic and thermomechanical calculation of a two-dimensional model of a gas turbine engine is a joint calculation of the hydraulics of internal cavities and air flow channels, obtaining air temperatures in these cavities and channels, and the subsequent application of these thermal loads to the materials of engine parts and assemblies. Next, the calculation of the thermal state, preparation and calculation of the mechanical model with obtaining displacements and clearances in the engine components of interest.
