“…Earlier experimental results on the H 2 /Cl 2 system include explosion limits H 2 /Cl 2 [130,131], laminar flame speeds [105], flame structure [132], and shock tube results [133]. Studies on the inhibition of moist CO oxidation by HCl in flow reactors [5,6,8] and chlorine inhibition in flames [124] were also presented.…”

“…Compositions, initial (P 1 ) and reflected pressures (P 5 ) of the tested mixtures are reported in Figure 6 shows the effect on the modeling predictions for mixture B of using the rate constant proposed by Leylegian et al [105], which is significantly above our preferred value. The use of the larger value of k 9 improves modeling predictions, with a 30% reduction of the calculated ignition delay times.…”

The high temperature chlorine chemistry was updated and the inhibition mechanisms involving HCl and Cl 2 were re-examined. The thermochemistry was obtained using the Active Thermochemical Tables (ATcT) approach, resulting in improved data for chlorine-containing species of interest. The HCl/Cl 2 chemistry discussed in the paper was based on reference and experimental measurements of rate constants available in the literature. By coupling the new HCl/Cl 2 subset with the Politecnico di Milano (POLIMI) syngas mechanism a kinetic mechanism consisting of 25 species and 102 reactions was obtained.The validation was carried out on selected experimental data from laminar flames, shock tubes and plug flow reactors. Systems containing Cl 2 showed high sensitivity to Cl 2 +M ⇀ ↽ Cl+Cl+M; the rate constant for this reaction has a significant uncertainty and there is a need for an accurate high-temperature determination.

The simulation of a flame assisted chemical vapor deposition (FACVD) process is here proposed with reference to the growth of silicon thin films through the silane/chlorosilanes/hydrogen/chlorine route. The goal is to design a reactor able to deposit micromorphous or multicrystalline films at the high growth rates necessary for photovoltaic applications. In fact, since FACVD processes can operate in atmospheric conditions and in auto-thermal mode, they present significant energetic advantages with respect to the plasma assisted technology used today. This work is in particular devoted to illustrate the multi-hierarchical modeling procedure adopted to determine the process optimal operating conditions and to design the deposition chamber. Different burner geometries (single, porous or multiple nozzles burner) were investigated in order to exploit the advantages of the two classical stagnation flow and Bunsen stretched flames.
