Повышение запасов газодинамической устойчивости многоступенчатых осевых компрессоров с нерегулируемыми направляющими аппаратами

Abstract

Redistribution of flow direction by changing the shape of the guide vane blades axis could favorably affect the work stage axial compressor and contribute to the improvement of mutual work of the multistage axial compressor stages. Has been performed a numerical study of special profiling for guide vane bend by circular arc in circumferential and axial direction. Simulations have been carried out on the basis of fluid dynamics computation in ANSYS CFX v. 12.1 in conjuction with the turbulent models and verification by test data.
