Overview

Wind tunnel experiments reveal how shock train and pressure fluctuate in concave channels versus rectangular ones, suggesting improved flow management.

Key Points

  • The concave channel showed more pronounced shock train characteristics and pressure stabilization compared to the rectangular channel.
  • Pressure fluctuations were concentrated in the frequency range of 2–1000 Hz, indicating complex interactions within the flow.
  • Wind tunnel tests were conducted at Mach numbers of 1.85 and 2.70 to analyze shock train behavior in different channel geometries.
  • Stronger anti-backpressure in the concave channel resulted in longer shock train travel and reduced flow separation distances.
