Abstract

In order to estimate the performance of partial casing treatments, this study improved the classic parallel compressor model, which divides a partial casing treatment compressor into a casing treatment sub-compressor and solid-wall sub-compressor in the circumferential direction. According to the characteristics of a partial casing treatment, the assumptions of the classic parallel compressor model were modified to conduct a performance prediction calculation for a compressor with a partial casing treatment. In this study, a transonic compressor was evaluated and compared using the experiment results. The research results indicated that if the characteristic lines of axial solid-wall and casing treatment compressors were given, this model could well predict the characteristics of the partial casing treatment, no matter what the proportion of the slot area was, and the results were found to be satisfactory.
