Abstract

Additive Manufacturing (AM) is set to be a game-changer in the design of internally-cooled hot gas components for gas turbines. AM allows for the much more intricate designs required for highefficiency, hydrogen-burning turbines. Therefore, the impact of AM on pressure losses and heat transfer in internal cooling channels is of acute importance to thermal engineers. In this paper, a new test rig for the measurement of the two above-mentioned parameters will be presented along with the measurement data for a selected number of tested geometries. These consist of test specimens with different hydraulic diameters (4 and 10 mm) and printing directions of 0°, 45° and 90° to the build plate. In addition, the numerical simulations of these geometries will be discussed. The focus is on the comparison with the experiments and matching with different roughness levels.
