| Summary: | This work is concerned with numerical computation of turbulent flow and heat transfer in experimental models of a radially rotating channel used for turbine blade cooling.
Reynolds-averaged Navier-Stokes and energy equations with a two-layer turbulence
model are employed as the computational model of the flow and temperature fields. The
computations are carried out by the software package of “CFX-TASCflow”. Heat loss from the channel walls through heat conduction is considered. Results at various
rotational conditions are obtained and compared with the baseline stationary cases. The
influences of the channel rotation, through-flow, wall conduction and the channel
extension on flow and heat transfer characteristics are explored. Comparisons of the
present predictions and available experimental data are also presented. |
