Low flow, low specific speed compressor stages are known to have inherently low performance level. Their low performance is attributed to a number of factors such as: high internal friction, disk friction, and leakage losses per unit mass flow. Comparative studies of design and performance indicated that it was possible to improve performance of the low specific speed compressor stages through the use of more favorable flow passage cross sections in the impellers. Use of wedge-shaped blades makes it possible to form such impeller flow passages. A major development program, started in early 1960’s, led to the emergency of the wedge-type compressor wheel as the wheel for low flow, low specific speed applications. The wheel is capable of operating in flow ranges previously designated for reciprocating compressors with an excellent operating range and good efficiency.
