“…After obtaining a steady mean flow, the disturbance flow field is computed by solving the linear disturbance equations following the approach in Browne et al. (2019). Disturbances are introduced employing volume forcing in m in the form where disturbances with a frequency of are introduced to excite second-mode instability waves.…”

“…A similarity profile is prescribed at the inflow of the computational domain, and an outflow buffer is placed at x = 17.8 m to reduce reflections at the outflow. After obtaining a steady mean flow, the disturbance flow field is computed by solving the linear disturbance equations following the approach in Browne et al (2019).…”

“…For larger initial disturbance amplitudes (i.e., q ∼ q) and/or when the disturbances reach the nonlinear transition regime, the nonlinear disturbance terms in the governing equations become significant and need to be evaluated to accurately capture the mechanisms driving transition. A more detailed discussion of the derivation and some of the intricacies of the disturbance flow equations and its numerical solution procedure are given in [35,50,51].…”

“…Over the last two decades, a number of methods for predicting the initial growth of boundary-layer instabilities on complex shapes in hypersonic flow have been developed. These methods include spatial BiGlobal analysis [14,15], plane-marching PSE [16,17], One-Way Navier Stokes (OWNS) [18], linearized Direct Numerical Simulation (LDNS) [19], forced DNS coupled with sparsity-promoting Dynamic Mode Decomposition [20], Wavepacket Tracking with Adaptive Mesh Refinement (AMR-WPT) [21], and Input/Output (I/O) analysis [22]. All of these methods are linear and 2 Distribution Statement A: Approved for Public Release; Distribution Unlimited.…”
