352 小型遠心圧縮機のサージングに関する研究(G05-6 流体機械(1),G05 流体工学)  [in Japanese] 352 A STUDY OF SURGE IN A SMALL CENTRIFUGAL COMPRESSION SYSTEM  [in Japanese]

This paper reports the experimental and theoretical study of the surge occurred in prototyping an ultra micro centrifugal compressor. As the first step, the 10 times size model of an ultra micro centrifugal compressor having the 40mm outer diameter was designed and manufactured. The detailed experimental investigations for the transient behavior of surge with several different values of B parameter were carried out. The experimental results during the surge were compared with those obtained by the non-linear lumped parameter theory in order to validate the effectiveness of the theoretical surge model for the micro centrifugal compressor. As a result, the quite different behavior of the surge appeared for the different values of B both in the experiment and the analysis.
