摘　　要：研究非线性流阻和作功机械内部摩擦对流体流动作功装置性能的影响,导出输出功率与机械效率以及功率损耗与机械效率间的关系,又由此导出最大输出功率及其相应的一些重要性能参数,并作些有意义的讨论.The effect of nonlinear flow resistance and internal friction in the mechanism for doing work on performance of a fluid flow power plant is investigated. The relations between power output and mechanical efficiency and between loss power and mechanical efficiency, the maximum power output and some corresponding important parameters are derived. Some significant analyses and discussions are done. The conclusions obtained may provide some new theoretical bases for the optimal design of a fluid flow power plant.
