The aim of this work was to evaluate experimentally and through numerical simulations, the helical path and the axial mean velocity developed by glass beads with diameter of 2.7 mm flowing with a non-Newtonian fluid through a partially obstructed annulus.
Techniques of computational fluid dynamics (CFD) were applied to obtain detailed information about the flow field, allowing to estimate the radial position of launching of particles in the range of 35.5 mm to 39.1 mm.
Techniques of CFD were applied in order to predict the flow patterns in horizontal annular sections partially clogged and compared with the experimental data obtained by inserting particles into the flow.
The simulations were performed steady, in laminar regime using periodic flow conditions in the axial direction.
The parameters of the Herschel-Bulkley model (=3.14 Pa; =0.3864 Pa.sn e = 0.50) corresponding to the fluid studied were inserted into the viscous panel of the CFD software.

In this paper, the local wind field of a container terminal in Shanghai of China was simulated by CFD technique, and the corresponding spatial distribution of wind velocity, turbulence intensity and wind profile were investigated in detail.
The results of the simulation suggest that the local surrounding wind field of the investigated container terminal is remarkably influenced by the surrounding container ship and container piles.
Fig.2 Schematic of a container terminal Fig.3 Meshed inner region and the definition of wind angle The computational domain of CFD was divided into two regions, i.e. the inner region and outer region, with the inner one surrounded by the outer one.
These simulation results suggest that it is not reasonable to use a constant power function index for the entire local wind field surrounding the port machinery.
