Summary

Infinite inorganic fibers can be manufactured by a continuous CVD process on a different core material. A mathematical analysis of the process has not been presented so far. This paper represents an attempt to develop a simple model incorporating all important parameters. The one-dimensional model including system chemistry, flow behavior, and mass and heat transport, is developed to simulate the CVD process on a core material. This model investigates the relative importance of different parameters affecting the deposition process. We also try to explain some of the defects forming on the substrate. The numerical results, which were obtained for typical operational conditions, give important clues for the reactor scale-up.
