Abstract :
The article describes the analysis of the
circumferential groove casing treatment in an axial
compressor. To analyze the Pressure across the rotor
blade of the axial compressor with and without
circumferential case grooving, the control volume near
the casing is divided into two parts: the control volumes
inside and outside the tip gap. The flow mechanisms of
stall margin improvement due to casing grooves in
NASA Rotor 67 are quantitatively analyzed. Based on
the axial distribution of the axial forces, the contribution
of groove to the stall margin improvement is assessed.
And the grooves that play a major role in stall margin
improvement are ascertained. The pressure across the
blade with case grooving is little bit higher than the
pressure across the blade without case grooving.
