DCE TEST MATRIX

Droplet Combustion Modeling Results

---

Summary of Calculations

Many of the experimental test points in the overall matrix for the Droplet Combustion Experiment (DCE) have been simulated using a time-dependent, finite element, chemically reacting flow model (Marchese, 1996). The calculations use a recently-developed n-heptane mechanism (Held, et al., 1997) along with detailed molecular transport. The calculations also consider the effect of non-luminous gas phase radiation (Marchese and Dryer, 1997).

The predictions shown here were performed in advance of the flight experiments to assist in the selection of test matrix conditions. The calculated results are presently being further refined in preparation for publication. If the reader is interested in quoting any of the results presented here, please contact Prof. Dryer.
