- W2334148437 abstract "A new method has been developed in order to estimate fluid velocity using tracer particles which do not follow the flow. The present PTV (particle tracking velocimetry) algorithm is an extension of Kalman filter-type velocimetry reported by Yagoh et al. (Yagoh, K., Ogawara, K. and Iida, S., Trans. Jpn. Soc. Mech. Eng., Vol. 57, No. 542, B (1991), p.3622) by which particle position measured in the presence of noise can be used to determine particle velocity. Although PTV is a common technique for flow measurements, one obvious shortcoming is noted. Namely, ordinary PTV algorithms could not be used when the particle density is different from the fluid density, because of ill-trackability of tracer particles. This may cause serious loss in accuracy when some forces cannot be neglected, for example, centrifugal forces of gravitational force. This study has proven that the new algorithm successfully identifies fluid velocity, and that it also has the ability to estimate particle diameter during the course of the tracking process." @default.
