Оптимизация параметрической модели входного регулирующего аппарата центробежного компрессора

Abstract

Research of influence of the basic geometric parameters on losses and aswirling flow in front of the impeller of the adjustable centrifugal compressor is performed. Parametrical models of the inlet duct and axial inlet guide vane (IGV) with rotary blades are developed.Numerical research was carried out in the software system ANSYS CFX with using the methods of the theory of design of experiments (DOE). An optimization of the inlet guide vanes with inlet duct where complex criterion function was minimization of total losses in IGV and the inlet duct at defined angles average integral swirl flow at the inlet of the impeller is solved
