Hypersonic Boundary-Layer Transition — 2D Wave & N-Factor Chart

2D eN-method chart of hypersonic boundary-layer transition: watch a Mack second-mode instability wavepacket amplify downstream, breaking down into broadband turbulent noise, alongside a live N(x) amplification-factor curve versus the critical threshold, as you tune Mach number, wall cooling, unit Reynolds number and environment noise.

The same eN-method physics as the 3D hypersonic transition lab, rendered as two 2D-native charts instead of a rotating vehicle: a live amplitude-vs-station trace of the Mack second-mode wavepacket itself, growing from a quiet laminar signal into an amplifying tone and finally breaking down into broadband turbulent noise, paired with the amplification-factor N(x) curve engineers actually plot against the critical N_tr threshold when they design a vehicle's thermal-protection system. Adjust Mach number, wall cooling, unit Reynolds number and environment noise to watch the transition station move exactly as it does on real hypersonic design charts.
