Investigation of Highly Pressurized Two-Phase, Reacting Flow.

摘要

A single-stage gas gun is used for simulating gun tube flows. The gas gun is driven by the combustion of gas mixtures consisting of H2/O2/He, H2/He/CO/O2, and CO/O2. Thus, the two main combustion reactions occurring in chemical gun propulsion are simulated. Experiments had the goal to improve the knowledge of reacting two phase (gas/solid) gun tube flows providing a data bank applicable for interior ballistic model validation. Parameters measured include pressure and temperature as well as velocity gradient at various positions along the gun tube. Multi channel near infrared spectroscopy measurements for recording the transient gas phase species were also performed.
