WebParticle tracking velocimetry (PTV) is a velocimetry method i.e. a technique to measure velocities and trajectories of moving objects. In fluid mechanics research these objects are neutrally buoyant particles that are suspended in fluid flow. As the name suggests, individual particles are tracked, so this technique is a Lagrangian approach, in contrast to … Web(2) Gas Flow. The differences between gas and liquid flow with respect to tracers are outlined. It was found that the isotope dilution method is too difficult. A special pump was devised for injecting a sample at pipe pressure without precompression. The results show that Sjenitzer's calculations for liquid flow apply also for gases. (D.L.C.)
