The estimation of initial data uncertainty influence on the calculated gas-dynamic characteristics of turbine blade row

The estimation of geometrical and physical variables uncertainty influence on the workflow in turbomachine blade row was carried out by the example of untwisted nozzle blade (NB). The flow in the nozzle blade modeling was carried out in a specialized software package NUMECA. The carried calculations allowed to give a qualitative and quantitative assessment of research problem, and to develop further areas of research.
