Abstract:

Experiments were conducted to determine the distribution of static pressure and lateral mass flow rate in a pin-fin trapezoidal duct that models the cooling passages in gas turbine blades. The ratio of lateral-to-total flow rate c was varied from 0.3 to 1.The flow Reynolds numbers were varied from to . The results show that: The pressure drop along chordwise is much larger than that along radial. The lateral flow rate near the root and the top of the blade is larger than that in the middle region. The lateral mass flow ra
