摘要 根据前置导叶轴流式推进器的结构与性能特点,改进水力性能试验方法,重新设计相关试验设备,准确得到多种静动间距下的水力性能曲线,验证数值计算结果,初步掌握静动间距对前置导叶轴流式推进器水力性能的影响规律。 According to the structure and performance characteristics of axial flow waterjet with front vane, the traditional test methods are improved and some relevant test equipment is redesigned. The hydrodynamic performance curves under various distances between the vane and impeller are accurately obtained and the CFD results are verified. The influence rule of distance between the vane and impeller on the hydrodynamic performance of the axial flow waterjet with front vane is preliminarily grasped.
