The paper describes a method for solving numerically two‐dimensional or axisymmetric, and three‐dimensional turbulent internal flow problems. The method is based on an implicit upwinding relaxation scheme with an arbitrarily shaped conservative control volume. The compressible Reynolds‐averaged Navier‐Stokes equations are solved with a two‐equation turbulence model. All these equations are expressed by using a non‐orthogonal curvilinear co‐ordinate system. The method is applied to study the compressible internal flow in modern power installations. It has been observed that predictions for two‐dimensional and three‐dimensional channels show very good agreement with experimental results.
