Abstract

One of the effective methods for improvement of compressor stage operation is a flow control within the compressor passages. An application of boundary layer control on the suction surface of a blade profile may be useful in tandem cascade configuration. Total tandem guide vane consists of a series of two vanes: guide vane (the first segment) and straightening vane (the rear segment). These vanes have a definite shift along the axial and peripheral direction, providing a perfect re-distributing of energy within the blade passages between different flow zones. There are several parameters influencing mainly on loss in a tandem cascade. Experimental results of the parametric test are used for the creation of a statistical model of loss determination of compressor tandem cascade using the Group Method of Data Handling (GMDH). The paper focuses on the statistical-based correlation that encompasses most pertinent parameters featuring tandem configuration and operating condition.
