| Abstract: | Particle Image Velocimetry(PIV)is often used to investigate the real time combustion flow field because of its ability to deliver instantaneous flow field information with high spatial and temporal resolution.In this paper the application of this measurement technique to methane coflow diffusion combustion was presented.Some problems such as particle seeding,flame luminescence,asymmetry of light intensity and data processing appeared during the measurement were analyzed and the means to solve them were presented. |
