Abstract: Flow and heat transfer phenomenon was numerically simulated for a shrouded disk with high positioned air inflow.Conjugate heat transfer calculation was carried out,based upon the mixing length turbulent model,to give prediction on flow field,temperature field and averaged Nusselt number of the disk face.The flow and heat transfer characteristics within the shrouded disk configuration was analysed.Comparison with experimental results was made.The results show that the developed mixing length model is applicable for simulations of shrouded disk with high positioned air inflow.
