Instead of assigning different shear rates, he employed different breakage rate expressions for the two zones. The problem of coupling population balance models with fluid flow models has received some attention recently and coupled PB-CFD models have been developed for a wide variety of processes such as fluidization [70], gas-liquid reactions in bubble columns [71] and nanoparticle synthesis in flame aerosol reactors [72]. Complete description of aggregation in turbulent environments requires simultaneous solution of basic balance equations for mass, momentum, energy and concentration of species present along with population balances for particles/aggregates of different size classes.

We performed gas phase photocatalytic oxidation reactions of hydrocarbons by flowing a known mixture of heated humid air with organic vapor through an annular reactor (25). We used nanostructured TiOj coated using flame aerosol technique at optimized process conditions, which enabled us to achieve higher conversions and selectivities dian obtained by coating prepared by other methods. 

Gas Phase Cyclohexanol and cyclohexanone are obtained with Ti02 film reactors produced by flame aerosol, with selectivity for the two products of 98 % [3].

The flame reactor is the one most widely used for the commercial production of inorganic oxide particles by aerosol processes. The aerosol precursor in the form of a vapor is... 

Thermal plasma synthesis has been used to make colloidal scale and nanoscale aerosol particles. The high temperature and inert atmosphere of the plasma enable the synthesis of materials that cannot be made in flame reactors (see, for example. Reference [46]).

Ultra fine M0O3 particles were prepared in a flame reactor which has already been described (ref. 6). It should just be recalled that the oxide aerosol is generated from the vapor of a volatile metallic compound (M0O2CI2 or M0Q5) which is injected into the burner fed with hydrogen and oxygen and then decomposed in the flame either by hydrolysis or by oxidation. The oxide issued ftom the flame reactor was treated at 673 K in air for 24 h (standard treatment) in order to eliminate residual chlorine and to transform all the M0O3 into the orthorhombic phase (see below).
