The present work experimentally investigates the conjugate heat transfer performance for a pin fin trailing edge channel for gas turbine blades. The effect of two main factors: material thermal conductivity and thermal boundary conditions, i.e. conjugate and convective boundary conditions, are quantified by comparing the nondimensional temperature and Nusselt number.

Seldom experimental has been conducted to investigate the conjugate heat transfer characteristics of pin fin channels for turbine blade trailing edge.

Results indicate that thermal conductivity can significantly impact the heat transfer capacity, i.e. Nusselt number; meanwhile, the necessity of taking conjugate heat transfer effect is demonstrated by comparison with purely convective results.
