title = "Numerical Investigations of Boundary Layer Instabilities on a Blunt Swept Flat Plate at Mach 6",
abstract = "Numerical Computations are carried out in order to investigate the linear (primary) instability mechanisms for a hypersonic boundary layer on a blunt, infinite swept flat plate at 0◦ and -7° angle of attack (AoA) and a sweep angle of Λ = 70°. The flow conditions of the Boeing/AFOSR Mach 6 Quiet Tunnel (BAM6QT) at Purdue University were chosen for the calculations. Linear stability theory (LST) predicts the amplification of the second mode, steady and traveling crossflow instabilities for both angles of attack, but slightly higher growth rates are found at 0° AoA. Maximum N-factors of # ≈ 8 and N ≈ 13 are computed for the second mode and for the traveling crossflow respectively at both angles of attack. Low amplitude so-called controlled forcing and preliminary low amplitude (linear) three-dimensional wavepacket computations are in good agreement with LST.",
