This work deals with the numerical solution of the transsonic flows through the two‐dimensional and three‐dimensional turbine cascade. The flow is described by the set of Euler equations using rotating frame of reference. In the first part we would like to mention some aspects concerning the theory of the so called TV‐stability for the case of a scalar hyperbolic equation. In the second part we describe a second order implicit finite volume method for general unstructured meshes and finally we present the results obtained for the three‐dimensional transsonic flow through the axial turbine cascade given by Škoda Plzeň.
