    2. Geometrical Details along Radial Direction True flow through a turbo-machinery is three-dimensional. The effect of the strong centrifugal forces are exerted by/on blades in radial direction. The centrifugal field distorts the flow velocity profiles considerably. Fluid particles tend to move outwards rather than passing along cylindrical stream surfaces as classically assumed. Particularly in low hub: tip ratio designs. An approach known as the radial equilibrium method, widely used for three-dimensional design calculations.

    3. Radial Variation Blade Geometry

    4. Radial Equilibrium Theory Assumes that flow is in radial equilibrium before and after a blade row. Radial adjustment takes place through the row. More important for Axial Flow Machines.
