A model for pulsation in high-speed double cone flow
Subhajit Das, Subrahmanyam Duvvuri
Periodic large-scale shock-wave unsteadiness over a canonical double cone, termed in literature as "pulsation," is experimentally studied at Mach 6. The general double cone geometr…
An aeroacoustic mechanism to explain universal behavior in hypersonic wake flow oscillations
Premika S. Thasu, Gaurav Kumar, Subrahmanyam Duvvuri
Recent experimental studies reveal that the near-wake region of a circular cylinder at hypersonic Mach numbers exhibits self-sustained flow oscillations. The oscillation frequency…
A model for frequency scaling of flow oscillations in high-speed double cones
Gaurav Kumar, Vaisakh Sasidharan, Akshaya G. Kumara +1
Coherent small-amplitude unsteadiness of the shock wave and the separation region over a canonical double cone flow, termed in literature as oscillation-type unsteadiness, is exper…
Strouhal number universality in high-speed cylinder wake flows
Premika S. Thasu, Subrahmanyam Duvvuri
Flow oscillations in the near-wake region of a 2D circular cylinder are experimentally investigated at Mach 6 over the Reynolds number range to . The o…
Large- and small-amplitude shock wave oscillations over axisymmetric bodies in high-speed flow
Vaisakh Sasidharan, Subrahmanyam Duvvuri
The phenomena of self-sustained shock wave oscillations over conical bodies with a blunt axisymmetric base subject to uniform high-speed flow are investigated in a hypersonic wind…
