Turbodrill with asymmetric stator and rotor vanes |
摘要 |
A turbodrill has rotor vanes and stator vanes that are asymmetric with respect to each other. The rotor blade on which the rotor vanes are disposed has a reaction of less than about 0.5. A method of designing a turbodrill comprises optimizing a first design of stator vanes and optimizing a second design of rotor vanes using computational fluid analysis.
