Abstract: |
The
two-dimensional, compressible, thin-layer Navier-Stokes
and energy equations were solved numerically to obtain heat transfer rates on
turbomachinery blades. The Baldwin-Lomax algebraic model and the q - omega low Reynolds
number, two-equation model were used for modeling of turbulence. For the numerical
solution of the governing equations a four-stage Runge-Kutta
solver was employed. The turbulence model equations were solved using an
implicit scheme. Numerical solutions are presented for two-dimensional flow
within two vane cascades. The heat transfer results and the pressure
distributions were compared with published experimental data. The agreement
between the numerical calculations and the experimental values were found to
be generally favorable. The position of transition from laminar to turbulent
flow was also predicted accurately. |
