Chemical Vapor Infiltration Design Optimization.

Abstract

The construction, execution, and experimental validation or a computer model for isothermal CVI processes. The feasibility of incorporating the model into a commercial CFD code, FIDAP, is investigated. Model validations were made using methyl trichlorosilane and hydrogen. Comparisons revealed encouraging agreement between the model predictions and experimental data. The model predicted the correct trends of the densification rate as a function of temperature and pressure while slightly overestimating the densification rate as a function of time. jg p.1
