Note:
Nowadays the development of axial flow compressors relies upon the use of Computational Fluid Dynamics (CFD). A 3-D Navier-Stokes methodology can be effectively introduced at later stages of the design in order to check the performance of the turbomachinery configuration in analysis. For the gas turbine matching a large number of solutions for different off-design conditions of the multi-stage axial flow compressor needs to be checked with fast computational models. So, at the early design stage, reduced order modeling tools are widely used in order to explore the design space of a new configuration: for this purpose 1-D, 2-D, throughflow and axisymmetric codes are useful tools.
In this paper a complete design/analysis procedure developed by the authors is presented. A design suite of codes, T-AXI, is coupled to the COMP1D code, a 1-D Time-Marching code for the design and off-design performance prediction. A single stage transonic compressor has been redesigned and then analyzed with the developed tools: the results are compared to the experimental data available in order to validate the methodology. Both aeronautical (E3) and industrial (V64.3A) multistage compressor design examples are presented.
