Numerical analysis of heat transfer in typical turbine blade cooling configuration of ribbed passage and pin fin arrays

  • Numerical simulation was used to investigate the heat transfer of a typical turbine blade cooling configuration of ribbed passage and staggered pin fin arrays. Numerical results indicate that the distribution of heat transfer coefficient lacks of uniformity in the pin fin region. Calculation shows that blade top and root regions have much higher heat transfer coefficient and so is the area near ejection holes, whereas much lower heat transfer coefficient is observed for the central region of the blade.
