Abstract
Paper presented at the 9th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Malta, 16-18 July, 2012.
The principle of the frequency modulation Doppler global velocimetry (FM-DGV) is presented in this paper. A FM-DGV system has been developed, of which a CCD camera was used as the detector to receive scattering light. The system was made up of a narrow band laser, a light-sheet-generating optics, an iodine cell, a frequency monitor unit, and an image acquisition CCD camera. Based on this system, measurements have been carried out on the velocity distributions of a rotating wheel. The results show that the system works well, and the maximum velocity measurement error is less than 2m/s.
