Dynamic Transition From Regular to Mach Reflection Over a Moving Wedge
Lubna Margha, Ahmed A. Hamada, Doyle D. Knight +1
The transition between the Regular Reflection (RR) and Mach Reflection (MR) phenomenon impacts the design of the supersonic and hypersonic air-breathing vehicles. The aim of this p…
Numerical Investigation of a Rotating Double Compression Ramp Intake
Lubna Margha, Ahmed A. Hamada, Othman Ahmed +1
The intakes of air-breathing high-speed flying vehicles produce a large share of the thrust propulsion. Furthermore, the propulsion performance of these engines increases when the…
Dynamic Transition From Mach to Regular Reflection Over a Moving Wedge
Lubna Margha, Ahmed A. Hamada, Ahmed Eltaweel
The design of supersonic and hypersonic air-breathing vehicles is influenced by the transition between the Mach Reflection (MR) and Regular Reflection (RR) phenomena. The purpose o…
Shock System Dynamics of a Morphing Bump Over a Flat Plate
Ahmed A. Hamada, Lubna Margha, Mohamed M. AbdelRahman +1
In this paper, the shock dynamics due to the movement of a bump over a flat plate flying at supersonic speed are numerically investigated. The bump is located at the impingement po…
