Different non-axisymmetric end wall profilings have great impacts on the aero-dynemic performance of turbomachinery. Therefore,the research on the method of end wall profiling becomes more and more important. This paper concentrated on the non-axisymmetric end wall profiling methods. At the beginning,domestic and overseas development history of the non-axisymmetric end wall was introduced.After that,all of the typical Non-axisymmetric end walls profiling methods were analyzed,and the profiling theory of each method was elaborated,and some key points were highlighted as well. By analyzing different objects,we further explored the applicability of different profiling methods and their effects on aerodynamic performance,the advantages and disadvantages of each method was pointed out. Finally,the development of Non-axisymmetric end wall profiling method was prospected.
