blade shape
 

Hello everybody

Can anyone tell me why shape (geometry) of axial compressor blades are more complex than Steam Turbine blades.

(1). I don't think so. (2). The pressure increases along the compressor path, at the same time, the Mach number decreases. So, it is sensitive to flow separation. (3). For turbine blades, the Mach number increases and the pressure decreases. So, relatively speaking, it is less sensitive to the flow separation. (4). Internal flow separation and prediction is still a very difficult subject.
