DESCRIPTION:Speakers: Adrian Rennie ()\nSpatially resolved\, X-ray diffrac
 tion with synchrotron radiation permits detailed maps of the alignment of 
 crystalline colloidal particles to be deduced and compared with fluid mech
 anics calculations of the flow. The angular distribution of diffracted int
 ensity from a given position in the pipe provides information about the or
 ientation distribution of the particles. Orientational alignment in a disp
 ersion of kaolinite particles has been investigated in several geometries.
  These include a uniform pipe\, at bends as well as a flow pattern that co
 mbines both shear and elongational stress\, namely flow at a jet created b
 y a 2 mm diameter nozzle inserted in a 6 mm diameter pipe [1\,2]. The alig
 nment is quantified and presented in terms of order parameters. The orient
 ation at different positions in a cylindrical pipe can be correlated with 
 the Peclet number at different locations. The cone-shaped nozzle provides 
 a jet of liquid giving a high degree of alignment of the particles that is
  uniform along lines across the conical section and constant in the small 
 straight-sided region at the exit of the nozzle. The vortex motion that ar
 ises from the flow with a modest Reynolds number could be determined as we
 ll as the tendency for some particles to align with their large faces perp
 endicular to the overall flow direction at the flat surface of the nozzle 
 outlet. Older studies will related to new challenges related to 3D-printin
 g polymer composites.\n\nhttps://lindico453.srv.lu.se/event/67/contributio
