Abstract
Three velocity components of the water flow in a model of a gas turbine combustor were measured using two types of developed FLDVs. In order to measure the third velocity component, that is, radial velocity, a small fiber LDV of 6 mm in outer diameter was developed and immersed into the water model. The flow structure of the primary zone was investigated by considering detailed velocity profiles. It was found that there are four characteristic flows in the combustor: the recirculating vortex, the reverse flow downstream of the bluff body, the reverse flow near the combustor wall, and the toroidal vortex at the center. The size of the recirculating vortex decreased and its position shifted upstream with increasing momentum ratio of the jet flow rate to the swirling flow rate. The flow velocities at the inlet boundaries were also measured for the study of the inlet condition of the numerical simulation in the upstream regions of the swirler exit and the primary jet ports.
