Abstract:

Aiming to have an exploration on application potential of the throughflow computation method for turbomachines based on the time marching, the research progress home and abroad is concluded, and several key issues of application of this method are generalized, including geometric description of blade blockage, simulation of blade force, discontinuity problems in blade leading and trailing edges, and shock capture. Different computation models are also compared. It is summarized that the throughflow computation method based on the time marching has many advantages compared to the traditional throughflow method, and thus has the potential to be a competitive tool in advanced gas turbine engine components design and analysis, as well as in total engine steady and transient state simulation. This method is expected to have much more improvements in the aspects mentioned above, although it has achieved great progress. It is believed that this method will be adopted as a new standard tool in turbomachinery design and analysis with further developments and improvements.

Key words: turbomachine, throughflow, time marching, blade blockage, blade force, discontinuity at blade leading edge and trailing edge, shock
