The finite element method is applied to The
two-dimensional, inviscid, compressible radial
equilibrium equation for axial compressors.
Isoparametric elements are used along with three-point
Gaussian integration for stiffness matrix evaluation.
The radial equilibrium equation is put into
quasi-harmonic form for stream function formulation
and results are presented using an isentropic flow
assumption. Axial velocity profiles at rotor and
stator blade edges are compared with published
performance data of the NASA Task-1 stage transonic
compressor and with numerical finite element results
of Hirsch and Warzee.
