| Περιγραφή: |
A method is described for calculating turbulent three-dimensional flows through diffusers. The pseudo-unsteady Reynolds equations, complemented by a mixing length type model of turbulence, are expressed in a curvilinear coordinate system and are discretized through space by a staggered grid technique. For the time integration, we apply an A.D.I. method, found by approximate factorization of a linearized implicit scheme. The numerical results are compared with experimental data for an axial diffuser and for a centrifugal compressor diffuser. |
