Theoretical and experimental investigations were made for the three-dimensional boundary-layer flow on a rotating propeller blade. The differential solution method was used to solve the laminar and turbulent boundary layer equations that were presented in a non-orthogonal coordinate system which rotates with the blade. The Reynolds stress tensor was modelled by an algebraic eddy-viscosity formulation. The equations were solved numerically using the finite volume method. To verify the calculation, the three-dimensional laser doppler velocimeter was used to measure local flows near the blade surface. The computed velocity components, not only chordwise ones but also streamwise ones, show good agreement with the measured ones. Finally, the influence of viscosity on propeller performance is discussed based on the comparison between computed and measured open-water characteristics.
