Flow establishment over rearward-facing steps in high enthalpy flows
Establishment of steady flows in areas of separation is of critical importance when experimentally studying hypersonic flows. The University of Queensland has two large scale expansion tube test facilities (X2, X3) capable of generating flow speeds up to 15km/s. In this paper flow establishment in X2 is examined for a flat plate and a rearward-facing step model and the results compared to those for existing flow establishment theories. It is found that separated flows can be successfully established in an expansion tube, with the results agreeing well with empirical relationships.
