| 摘要： | Specific expressions for a general tensor description of the full field equations for flow about a propeller blade are given. Two orthogonal blade-surface coordinate systems Reconsidered: one consisting of the normal and constant radius lines and one consisting of the normal and constant fraction-of-chord lines. The third direction is obtained by the cross-product of vectors in the two given directions.It is believed that the first coordinate system is appropriate to describe the flow over the majority of the blade, and the second coordinate system may be better suited to describe the flow at the leading edge. It is recommended that the boundary-layer limit of the field equations be determined and numerical evaluations be conducted to explore the merits of the two coordinate systems. |
