Partial height guide vanes are adopted to improve non-uniformity of the diffuser flow in high specific speed centrifugal compressors. In order to get the optimum guide vane height, pressure and velocity fields were measured for five kinds of guide vanes using laser-two-focus velocimeter. The diffuser with guide vanes whose height is 40% of the diffuser width shows the best pressure recovery : its increment is 10% compared with the diffuser without guide vanes. The measurement of the velocity fluctuation in the diffuser reveals that the fluctuation decreases rapidly between the impeller outlet (D_2) and 1.1×D_2, decreasing slowly thereafter.
