Scramjet Flowpaths

Overview of Scramjet Research


The hypersonic flight environment provides numerous challenges in achieving sustained combustion with air-breathing propulsion systems. Two particular transient phenomena of interest are the processes of mode-transition and unstart. The objectives of this study are:

  • Understand the role of shock/boundary-layer interactions during these transient processes
  • Explore the large-scale structures present in these flow fields and their connection to SBLI
  • Evaluate the evolution of separated regions and their contributions to such events

Carefully-tailored, time-accurate RANS simulations are computed with validation against the available experimental data.
