Description

при йеИзМеннЫх радиальных размерах koMпрессора . Укороченные лопатки снижают интенсивность отрывных течений в пристенных сло х, сохран   высокий КПД диффузора. Сужающийс  входной участок диффузора способствует устранению перекоса радиальной составл ющей скорости и ее выравниванию в меридиональной плоскости, что позвол ет избежать отрыва потока с передней стенки на входном участке диффузора. За счет безотрывного течени  повыщаетс  статическое давление за диффузором и его КПД, а следовательно, КПД и напор центробежного компрессора.at yEASYMEnn radial dimensions koMpressor. Short blades reduce the intensity of separated flows in the near-wall layers, while maintaining a high efficiency of the diffuser. The tapering inlet section of the diffuser helps to eliminate the skewing of the radial component of the velocity and its alignment in the meridional plane, thus avoiding separation of flow from the front wall at the inlet section of the diffuser. Due to the continuous flow, the static pressure behind the diffuser and its efficiency, and hence the efficiency and head of the centrifugal compressor, increase.
