The blades are considered either solid, with heat conduction, or with a cavity held at constant temperature above the total temperature of the fluid. The surface of blades is hydraulically smooth or rough. The mathematical model is based on Favre averaged Navier-Stokes equations with SST turbulence model. The heat transfer inside blades is governed by Laplace equation for temperature. The solution for fluid part is obtained by implicit AUMPW+ finite volume method. The solution of Laplace equation is obtained by finite element method. The coupling between the two solvers is discussed including some problems. In the discussion of results, the effects of heat conduction in the blade, internal heating of the blade and surface roughness are observed.
