- Summary
- This program involves modeling the chemical vapor infiltration (CVI) of tube shapes in support of experimental process development at Oak Ridge National Laboratory (ORNL). The previously developed tube model, including radiative heat transfer, has been modified to match the new, larger reactor at ORNL. For infiltrating tubes 4″ OD and 12-18″ L, higher reactant flow rate is needed for rapid densification. Two new processing schemes are being investigated. In the first, the processing parameters - temperature, flow rate, etc. - are varied through the run in order to maintain optimum densification performance. in the second, processing conditions near the end of the run are adjusted to close residual porosity and to produce a gas-tight tube. For each of these, model runs will identify process schedules prior to experimental runs at ORNL.
