| Abstract: | A three-dimensional Navier-Stokes simulation was performed numerically for a transonic turbine planar cascade and a transonic turbine annular cascade using CFD software CFX-TASCflow code.The results show that CFX-TASCflow code software could predict reliably turbine cascade flow field and its performance.The characteristics of the researched transonic turbine cascades viscous flow field were analyzed. |
