A New Technique

A new technique for velocity-field measurements in fine granular systems is introduced. The hot-wire anemometry, mainly used for gaseous flows, is applied to nanopowders and is found to be a viable experimental method for flow measurements. A generic chute flow of aluminum oxide C and Aerosil A-90 and A-380 powders through a vertical channel is chosen as a test platform, and the results suggest that the hot-wire anemometry is a favorable option for nanopowder measurements.

Volumetric Flowrate

The design of a new solid particle seeding generator for laser-based velocity measurements in gaseous flows is reported. Performance tests revealed that the new seeder has the ability to control the concentration of seeding particles in a flow independently of the flowrate. It also can provide a steady supply of seeding particles, operate over an extended range of flowrate, and break up agglomerates into smaller particles. These features give this seeder advantages over its counterparts, especially at low volumetric flowrate.
