HEAT TRANSFER AND PRESSURE DROP IN A CONVERGING LATTICE STRUCTURE FOR AIRFOIL TRAILING EDGE COOLING

摘要

Lattice-matrix structures have distinct advantages in enhancing heat transfer in the cooling channels of a gas turbine blade. Lattice structures not only enhance heat transfer coefficient but also provide structural rigidity to the turbine blade. Stationary tests were performed for a 12 times scaled up model at four Reynolds numbers (4,000
