摘要	Flow resistance and heat transfer coefficients of typical double wall laminated film cooling configuration within a turbine vane were experimentally studied.The specimen was in large scale,and made of transparent organic glass.Laminated configuration consisted of double wall laminates,pin-fins,staggered arrays of impingement and film holes.The number ratio of impingement holes,pin-fins and film holes was 2∶1∶1.Five experiment vanes were installed in static cascade,and experiments were carried out under constant heat flux.Re of internal cooling air in the experiment was from 10~4 to 2×10~5,and Re of external fluid was from 10~5 to 3×10~5.The experiment results show that flow resistances of front channel and back channel of the vane are in the same level,and both of them decrease as Re of cooling air increases.Nuof front channel is slightly higher than that of back channel.Both of them increase as Re of cooling air increases.And experiment results were obtained from experiment vanes were compared with that obtained from laminated flat plates,and the tendency of the results agrees well.
