Fluid flow and heat transfer characteristics in the leading of blades at rotating state

  • Numerical simulation was performed to study the cooling configuration in the leading of blades at rotating state. The configuration was consisted of entering gas cavity, trailing edge and leading edge blocks. Computation was carried out for the different rotating velocity. The influence of rotating velocity on the fluid flow and heat transfer characteristics of this configuration was carried out. To impinging flow along the blade with outflow film under rotating state,the conclusion of numerical computation is given as follows:The heat transfer of the leading and trailing impingement surfaces are enhanced with the rotating velocity increasing. The heat transfer at the blade trailing impingement surface is stronger than at the leading impingement surface. The difference of heat transfer between the leading and trailing impingement surfaces decreases with the rotating velocity increasing.
