So it is necessary to study the flow structure in the riser.
Numerical simulation can provide some flow structures and solid distribution data not easily obtained in cold model experiments.
The radial profile at 0.2 m shows clearly a core-annulus structure with dense near-wall area and dilute core area.
But at the radial profiles above the height of refeed pipe orifice (400mm), the core-annulus structure is more irregular as the height is increasing, the core area sway.

Introduction Metal oxides play an important role in many areas of chemistry, physics, and materials science.
These multiple layers of nanopetals were connected to each other through the center to form 3D flower-like structures.
When no TBAB was added as a surfactant under the same reaction conditions, the precursor had an irregular structure of different sizes instead of a loose flower-like structure, as shown in Fig. 2.
After calcination, each petal of the flower-like structure had been transformed into a highly porous structure consisting of interconnected nanoparticles.
The TEM images shown in Fig. 3(c) further verified that this flower-like structure was highly porous and consisted of many interconnected nanoparticles, and the whole structure was on the micrometer scale.

Water samples were collected to monitor water chemistry of major ions and minor ions comprising inorganic pollutants such as fluoride, phosphates, nitrates and trace element as cadmium.
This basin has several aquifers with various capacities due to their lithological constitution, geological structure and operating facilities.
It has been shown that the bentonite is more than 65% consisting of montmorillonite and the chemical composition (Table 1) revealed that the percentages of major oxides in the clay structure are those of aluminium and silica.
