摘要

AbstractThe tandem cascade can be used as an efficient way to improve the compressor load. As for the interaction parameters between two rows of the tandem diffuser, it is known that the relative circumferential position, radial gap between two rows, ratio of chord length of two rows, difference of the stagger angle between the front row and rear row blades have significant impact on the performance of the tandem cascade diffuser. In the literature, there is a lack of references for evaluating quantitatively the influence of important tandem design parameters on the tandem diffuser, and thus the adjustment ranges of the tandem parameters cannot be determined accurately. In order to investigate the influences of the tandem design parameters on the compressor performance, in an economically affordable manner, the influences of the design parameters for the tandem cascades diffuser were investigated by Design of Experiments (DOE) method. The orthogonal experimental designs are performed for the radial gap R ...
