Formatted Abstract/Summary
The expansion tube is our tool of choice for producing radiating, high-enthalpy flows relevant to the study of re-entry aerothermodynamics. First, we describe the operating principles of a free-piston-driven expansion tube and two example facilities that have been constructed at The University of Queensland. These have been applied to a range of aerothermodynamic studies and a large effort has also been put into the development of instrumentation, including surface measurements, optical and spectrometric instruments. Two situations are described where radiating and ablating flows have been created, using both preheated hot walls and walls heated by aerodynamic processes during the test.

The detailed flow in these expansion tube facilities turns out to be quite complex and computer models are needed to completely and accurately describe the experimental flow properties and to diagnose the gas dynamic behaviour of the machine when developing new operating conditions. We describe two of the specialized flow simulation codes that we have written to assist us in our experimental work and look at the application of these codes to the expansion tube experiments.
