    2003-10-20 · Mitsubishi scaling philosophy uses the same turbine airfoils for rows 1 and 2 for 50Hz and 60Hz applications (i.e. the same respective blade and vane geometries between the M501G and the M701G gas turbine). Improvements in aerodynamic airfoil shapes were achieved using fully three-dimensional viscous Euler analysis.

  • The Effects of Blade-Row Spacing on the Flow Capacity of a ...

    2014-12-16 · The results show that for axial spacings above 50% of the upstream axial blade chord, simple wake mixing alone fully accounts for the upstream flow losses and a simple mass flow rate correction based on the rotor face mass averaged total pressure is sufficient. At spacings closer than this, other effects or loss mechanisms may be present.
