The Effect of Pin Fin at Trailing Edge on Heat Transfer of Turbine Blade

The numerical study was carried out on the trailing edge cooling of turbine blade using the circular pin fin that was arranged in cross type.The CFX software package was used to solve the aero-thermal coupling of this cooling scheme,and then the changes of temperature field,flow field and heat transfer coefficient were analyzed in detail.The results showed that the effect of pin fin on heat transfer was obvious.
