2、 the dynamic action of blades attached to a rotating shaft.An open systemFluid is continuous from inlet to outlet Fluid can flow through in either directionThe fluid is never contained in a closed cavity with bladesPath is partially obstructed by blades attached to a shaftAlways two or more blades,u

3、sually arranged symmetrically about the shaft on a rotating shaftThe shaft rotates,moving the blades relative to the fluid and energy is transferred by dynamic effectThe action of the blades on the fluid is dynamic（i.e.due to relative motion and dynamic pressure）,General definition of a Turbomachine
