✦ Synopsis

This paper presents numerical methods for solving turbulent and two-phase transonic ow problems. The Navier-Stokes equations are solved using cell-vertex Lax-Wendro method with artiÿcial dissipation or cell-centred upwind method with Roe's Riemann solver and linear reconstruction. Due to a big di erence of time scales in two-phase ow of condensing steam a fractional step method is used. Test cases including 2D condensing ow in a nozzle and one-phase transonic ow in a turbine cascade with transition to turbulence are presented.

Consideration is given in this paper to the numerical solution of the transient two-phase flow in rigid pipelines. The governing equations for such flows are two coupled, non-linear, hyperbolic, partial differential equations with pressure dependent coefficients. The fluid pressure and velocity are
