Note (General): The steady inviscid compressible flow through the two-dimensional cascade is computed by the Method of Time-Dependent Finite Area with hexagonal integral domain. Three different equation systems are considered which are physically equivalent under two assumptions: i) steady state, ii)subsonic or exsting weak shock flow field. The basic system is composed of the continuity equation, the Eular equation and the energy equation. Their differences during numerical behavior approaching the steady state have been examined through computations. To prevent the pressure or the density from becoming negative, the spatial averaging for smoothing was used, which appears to have some artificial viscocity and damping factor for time-dependent computations. In the steady state computed airfoil pressure distributions have shown good agreement with experimental measurements and there have been few differences among the three equation systems.
