Design Optimization of a Multistage Axial Flow Compressor Based on Full-Blade Surface Parameterization and Phased Strategy

Table 3

Performance at the design point before and after optimization in the first phase.

Design point	Mass flow (kg/s)	Total pressure ratio	Adiabatic efficiency	Surge margin
Original blade	112.1	3.54	0.8207	10.2%
Optimized blade	112.7	3.55	0.8255	15%
Relative change	+0.54%	+0.28%	+0.48%	+4.8%
