ABSTRACTA review is made of some of the mathematical modelling work carried out over the last few years with the objective of computing the flow and temperature fields for different thermal plasma systems. Typical results are given for d.c. plasma jets, transfered and non-transfered arc plasma reactors and for inductively coupled plasma torches. This is followed by a brief discussion of the important problem of plasma-particle heat transfer.

ABSTRACTA mathematical model for the analysis and design of inductively coupled plasma torches Is presented. The model is based upon a solution of the electromagnetic vector potential equation and is capable of predicting the two-dimensional velocity, temperature, and electromagnetic fields as well as the reaction kinetics inside the torch for any axi-symmetric coil configuration. The model is used to study the effect of coil geometry on the thermal decomposition of silicon tetrachloride to silicon. The coil geometry Is found to affect both the temperature field and the flow field and to have a significant effect on the reaction kinetics in the torch. It is demonstrated that through fundamental changes in the coil design It is possible to control the location of the reaction zone and to prevent silicon deposition on the wall of the reactor.

Antibacterial Material

Inorganic antibacterial materials consist of the antibacterial ions, the additives and the carrier. In this study, we synthesized a new inorganic antibacterial material, of which Ag+ was selected to be the antibacterial ion, lanthanum nitrate served as the additives, and the white carbon black was chosen as the carrier, which was prepared by a sol-gel method. The as-synthesized antibacterial material was characterized by inductively coupled plasma, particle size measurement instrument, and enumeration tests. The result showed that this material has loose and dispersive structure, good thermal and light stability. The possible antibacterial mechanism was also proposed through all the experimental data in this study.
