Vorticity dynamics theory and analysis method for compressor of gas turbine was described

and the mathematical and physical relations of total performance parameters and two important vorticity parameters was constructed based on vortictity dynamics theory. The analysis and optimization method based on boundary vorticity flux(BVF) and circumferential vorticity(CV) was researched. The multi-stage axial compressor of gas turbine was designed firstly and then analyzed using this theory and method

and the improving way for the designed compressor was found. It is demonstrated that CV can probe the high loss region near solid boundary

and the loss will be controlled if CV peaks can be restricted in the region near solid boundary. The swirl distribution can be optimized to control CV distribution

and in the optimization of the transonic compressor rotor based on CV the peak efficiency is improved by 1.13%. On the other hand

it is shown that BVF can reflect the vorticity source on solid boundary

and the vorticity and flow separation are suppressed through controlling BVF

and the rotor peak efficiency can be increased by 1.12% in the optimization based on BVF.
