| Popis: | A simple single-beam transit timing velocimetry (TTV) method has been developed for determining particle size and mean speed measurements. The method uses a single-beam light scattering system with the addition of two commercial nuclear instrumentation modules to obtain timing information from the trailing edge of the scattering pulses. Results of test studies show that the modal value of transit time remained constant over a wide range of particle sizes, even for particles approaching 50% of the total beam width. Applications of the TTV method to combustion systems include studies of liquid-fuel laminar flames, where integrated reaction times, and thus local droplet velocities, are needed in addition to particle size information. |
