- Abstract
- A Comparison of near-wall treatment methods using different turbulence models for heat transfer over a gas turbine nozzle guide vane were presented. Wall-function method, low Reynolds number method and transition model wear used. Predicted turbine vane surface pressure distribution through the near-wall treatment methods showed only a small difference of 1% approximately. But predicted vane surface temperature showed a significance difference of maximum 8%. Overall, reynolds stress turbulence model with wall-function method predicted the vane metal temperature and heat transfer coefficient fairly well.
