    Abstract
  • Numerical simulation was performed for the internal cooling passage of turbine blades with triangular pyramids, and the focus was put on the flow and heat transfer characteristics in the cooling passage, with respect to the differences between cases of windward and leeward conditions, aligned and stagger arrangements, different horizontal columns and different streamwise spacing ratios. Results revealed that the decrease of pressure loss and improvement of heat transfer efficiency attributed to the longitudinal vortex generated by the triangular pyramids. The case of leeward condition with aligned arrangement had the highest comprehensive heat transfer efficiency, which was 20%-30% higher than other cases; while in this case, the most suitable number of horizontal columns was 5, and the streamwise spacing ratio was 4-6.
