Abstract

Centrifugal compressors often use shrouded impellers for high pressure applications that demand reduced tip clearance losses and higher efficiency. Although manufacturing techniques such as casting, machining, 3D printing have been used to make shrouded impellers, they are not feasible for very small sized impellers. The proposed method uses a two-piece impeller design with a bladed disk and a slotted shroud. The two pieces are then welded with an interlaced joint between blades and slots to form the shrouded impeller.
