Abstract

In this work the application of CVD technologies for coating of fibrous substrates is addressed. The transport phenomena occurring in the reactor chamber are modeled in terms of conservation laws. The resulting mathematical model is solved by means of the GFEM. Two- and preliminary three-dimensional results are reported in the actual range of experimental conditions. Based on boundary layer assumptions for the gas phase, a one-dimensional "moving boundary" model for the deposition surface is formulated. Characteristics of fibers manufactured in the laboratory are presented and model predictions are analyzed. Several design and operation problems are pinpointed and further modeling studies are outlined.
