| Abstract: | In order to control and suppress instabilities caused by swirling flow, the authors have proposed a very simple passive method utilizing shallow grooves mounted on a casing wall parallel to the pressure gradient. The grooves is termed a "J-groove" and was theoretically analyzed and experimentally proved the capability of suppressing rotating stall in a vaneless diffuser. In continuation, this work is aimed at realizing experimentally the effect of J-grooves on suppressing rotating stall in the vaned diffuser of a centrifugal turbomachinery. Thirteen double curve vanes with various radial positions, various setting angle and J-grooves of different dimensions are tested in a parallel wall vaned diffuser with a semi-open radial impeller with and without J-grooves. The results show that J-grooves can also suppress rotating stall in the vaned diffuser for the entire flow rang. |
