Abstract

The aero-thermal properties of the flow field downstream of an NGV cascade of a three-sector combustor simulator rig are characterized by means of five-hole probe / temperature sensor measurements as well as laser-optical FSM-FRS diagnostics. Both methods are applied to acquire and analyze pressure, temperature and velocity information in a cross section downstream of the NGV. The study discusses current capabilities as well as limitations of both methods when being applied to turbomachinery configurations. In general, results obtained with both methods are on a similar absolute level. Based on a more detailed analysis, strong evidence for an intrusive interaction between the five-hole probe and the flow downstream of the NGV is found, which is significantly influencing the probe's measurement accuracies.
