Prior hypersonic research on local thermal forcing and instability behavior in boundary-layer transition studies.

  • Prior Work
  • CFD
  • High-Order Methods

Problem Statement

Localized thermal perturbations can alter instability growth in hypersonic boundary layers.

Why It Matters

This work remains part of prior technical foundation in high-speed CFD analysis.

Methods / Numerical + ML Setup

  • Modeled local thermal-strip perturbations across representative conditions.
  • Tracked instability response and compared against reference setups.

Key Results

  • Reported clear instability-response shifts under selected thermal-strip conditions.

Toolchain

  • CFD
  • Flow diagnostics
  • Scientific plotting

Challenges and Lessons

  • Maintaining fair comparisons across perturbation cases.

Future Work

  • Retained as foundational technical context alongside current DRL-CFD research.
