In the first report, the results of numerical studies for viscous flow passing through a two-dimensional supersonic cascade are reported. There, the flow instability called as forward traveling fluctuation with oscillating passage shock was shown. The present study reports the results of inviscid flow calculations in order to clarify the contribution of viscosity to this type of the flow instability. Results show that this type can occur also in inviscid flow. In reference (2)〜(9), shock fluctuation is explained as the interaction of the boundary layer/trailing vortex fluctuation. This type found in the first report may be another type of flow instability since it can be predicted also in inviscid calculations.
