Novel experimental phenomena of fine-particle fluidized beds [PDF]
, 2007 The dynamic response of bed height and concentration waves in liquid-solid fluidized beds to a step change in the fluidization velocity is considered. We experimentally study the liquid-solid fluidized beds, spherical beadings, with sizes ranging from ...

Soft theorems for two-scalar sigma models
Journal of High Energy PhysicsIn this paper, we study the scattering amplitudes and soft theorems for the sigma models with two scalars. We show that if the particles are Goldstone bosons, then you necessarily get Adler zero with no possibility for non-trivial soft theorems.

Fine particle turbulence modulation
, 2011 Streamwise turbulence intensities of fine particulate suspensions were studied in a 26 mm N.B. horizontal pipe loop. Colloidal silica spheres were prepared in 10-4M and 1M KNO3 solutions to control the degree of aggregate formation in the suspension ...
