High-speed air intakes often exhibit intricate flow patterns, with a specific type of flow
instability known as 'buzz', characterized by unsteady shock oscillations at the inlet. This …

The variable geometry supersonic inlet tends to decrease the throat area to reduce the Mach
number upstream of the terminal shock, so as to reduce the flow loss. However, excessive …

The detailed design steps and the idea of connecting M-flow and truncated Busemann flow
are given in this paper. A new improved method is proposed to effectively reduce the size of …

In practical aerodynamic problems, curved shock/boundary layer interaction (CSBLI) is more
frequently encountered than the canonical shock/boundary layer interaction (SBLI). Owing to …

Ramjet propulsion is commonly preferred to power supersonic and hypersonic vehicles for
cruising faster than Mach 3. This is an elegant solution owing to the lean architecture which …

Hypersonic air-breathing vehicles, utilizing ramjet and scramjet propulsion systems, are
emerging as a promising option for future hypersonic transportation due to high specific …

Conceptual design studies performed with reduced-order approaches allow feasibility and
sizing considerations of air-breathing engines to be configured at an affordable …

The thermal and chemical non-equilibrium effects on the flow structures and performance of
a hypersonic inward-turning intake, for the airbreathing scramjet propulsion, are numerically …

Wavecatcher (inward-turning) intake flows, at design Mach 12, are investigated numerically,
