Abstract

The effect of fluid flow in the CVI reactors on the deposition velocity and quality is very important. The visualization of perplexing and invisual fluid flow phenomenon in simulation-CVI reactor can be realized using the smoke generator based on forming TiO2 by reaction between TiCl4 and H2O. The smoke generation system fulfills these requirements, adjustable rate and density, long-time visualization of highly turbulent flow and uniformity of smoke while preserving simplicity of construction and operation. The flow field photographs demonstrate the effectiveness of the smoke generator, and the color, density and quantity of the smoke are very good for application to flow visualization studies for CVI reactors.
